The Top 5 Quality Issues with Cheap Fasteners

Purchasing managers must always keep their budgets in mind when buying fasteners. But when you’re too focused on price, you might sacrifice quality. And regardless of the application at hand, sacrificing quality is unacceptable. Your first priority should always be quality. If you choose to buy cheap fasteners to save a few bucks, you might be faced with a slew of quality issues that will actually cost you more in the end—in labour costs, operational expenses, and a bad reputation.

Here are the top five quality issues you’ll have to deal with if you go with cheap fasteners for your application.

Product Failure

When you buy cheap fasteners, you risk manufacturing a defective product. It doesn’t matter how great your product is if the fasteners used to hold it together aren’t right for your application. If your fastener is just a fraction of a millimeter off from your original design, you’ll be in trouble.

When manufacturers create cheap fasteners, they’re not too concerned with ensuring that the nuts and bolts they create match your design perfectly. They won’t test them to make sure they’ve been manufactured to your exact specifications. They have a “good enough” policy that you simply cannot afford if you’re in the business of selling high-quality products.

Lack of Durability

When people buy products, they want them to last. But if you’re placing cheap bolts and screws in your applications, you’re not giving your customers the durability that they expect. It won’t take long before your bolts and screws weaken and break due to wear and tear, which can render your product useless in no time. Give your clients their money’s worth by ensuring that you manufacture products that will last for the long haul. No one wants to be forced to replace fasteners within a few short weeks or months of buying a product.

No Strength

Fastener strength is especially important when it comes to industrial applications. If you buy cheap fasteners to hold together industrial equipment, they simply won’t have the strength to withstand the pressures being placed on them. They’ll most likely be made of cheap materials that won’t be strong enough for your application. A big load can snap a cheap fastener in half.

They Won’t Withstand Environmental Conditions

Chances are if you’re buying cheap bolts and screws, the appropriate plating and surface coatings won’t protect them. That means they’ll be susceptible to corrosion. They won’t be able to withstand the elements. The moment they’re faced with any type of moisture, they’ll start to rust, which will weaken them considerably. And if they’re not manufactured properly, they’ll likely be covered in tiny holes and gaps that suck in moisture quickly.

Difficult Installation

When you buy cheap nuts and bolts, you’ll find them a lot more difficult to use. They’ll be more likely to break during installation, which can cause frustration and increase your operational and labour costs. Not to mention you’ll have to replace those broken fasteners before your products even get out the door, which means you’ll be spending more money buying the same fastener twice.

Cheap Nuts and Bolts Cause Myriad Problems

The problems you’ll be forced to deal with won’t be worth the money you’ll save up front with cheap fasteners. You’ll not only have a whole bunch of unhappy customers who might choose never to do business with you, but you’ll probably have to deal with negative reviews and bad press that can damage your profitability for a long time in the future. Plus, depending on your application, you could be putting people who use your products at risk if your product fails.

What Is the Best Finish for a Rivet?

Rivets can be manufactured in several different materials, including general purpose aluminum, soft setting aluminum for vulnerable materials, harder aluminum for higher tensile and shear strength, malleable aluminum for brittle and soft materials, general purpose steel, stainless steel for clinical or hostile environments, nickel copper alloy for high temperature environments, or copper for thermal or electrical conductivity.

The type of plating or coating that will be placed on your rivets for added protection against the elements will be directly related to the type of material they are made of, which environment they’ll be placed in, and which elements they’ll need to be able to withstand—and at what frequency. Your budget will also be a factor in your decision.

Choosing the right finish for your rivets isn’t a simple and easy task. Many factors must be considered in order for you to make the right decision for your unique needs. Though there is no “best” finish for a rivet, you do have many different options to consider.

Cadmium

Plating a rivet with cadmium is done through baking by electrodeposition. It provides a pleasant appearance.

Zinc

Zinc plating, also known as electroplating, is pretty common. Your rivet is hot dipped, or galvanized, in the zinc salt solution and then met with an electric current. It will continuously provide corrosion resistance because zinc will migrate to uncoated areas. It is aesthetically pleasant, cost-effective, and thinner than other types of finishes. This type of plating is ideal for rivets that won’t be placed in harsh conditions.

Nickel

Nickel plating is one of the oldest protection methods. However, it tends to be more expensive than zinc or cadmium plating, so it might be out of your budget.

Phosphate

Your rivet will be submerged in a bath of phosphoric acid to be coated with this type of plating. Phosphate plating is ideal when you want to paint your fasteners or dip them in oil or wax for further corrosion resistance.

Silver

Silver plating can be quite expensive but it is still commonly used in the aerospace industry or for applications where a dry lubrication is needed on top of the corrosion deterrence.

Passivation and Preoxidation 

Passivation and preoxidation are necessary prior to assembly for stainless steel rivets or you risk the creation of oxidation or galvanic corrosion in a joint.

Anodizing

Anodizing is used for aluminum rivets—it protects them for saline corrosion agents as well as abrasion. Additionally, they can be tinted in many different colours to suit your application.

Dacromet

This non-electrolytic, water-based dry film will effectively protect against corrosion and chemical and mechanical damage. If your rivet will be placed in a high-temperature environment, then Dacromet, with its galvanic action, passivation, and self-repairing features, will provide the greatest form of protection.

JS500

If you’re concerned about your rivet plating negatively affecting the dimensions of your application, then JS500 may be your best bet. This electrolytic zinc finish is quite thick so it can cover any blemishes on your rivets in order to better protect them from corrosion, without changing the dimensions of your product.

JS Plus

JS Plus is not only cost effective but it’s also one of the most superior options for corrosion resistance. It can significantly increase the lifespan of your rivet.

Your Manufacturer Can Guide You

If considering the different types of plating options is overwhelming to you, you can request help from your manufacturer. When you work with a high quality, reputable fastener manufacturer, you don’t have to be left alone to make important decisions. Your supplier will provide you with the pros and cons of each rivet finishing option and guide you through your decision to ensure you choose the right one for your application. Because reputable manufacturers use thorough corrosion resistance testing procedures, you’ll be able to effectively protect your rivets with the right type of finish.

How to Prevent Corrosion on Your Fasteners

Corrosion is the cancer of fasteners. It can not only harm their appearance but it can lead to their total failure. And if your fasteners fail to do their job, the application they are in won’t be structurally sound, which can lead to bigger issues, like safety risks and additional costs.

As a purchasing manager, it’s important for you to understand what corrosion is, how it happens, and how to prevent it. To help you make the right choice when it comes to your fasteners and their corrosion protection, here’s some helpful information.

What Is Corrosion?

When it comes to metals, corrosion is an inevitable problem that must be dealt with. Simply ignoring it won’t do you any good in the long run—it’s going to happen, so you must be prepared for it.

Corrosion is the degradation of a metal’s properties. It is primarily caused by moisture, which causes electrochemical reactions in the fastener. Once an iron surface that is exposed to air makes contact with water, it is made rich with oxygen. Because the inside of the water drop has no oxygen, electrochemical differences occur. An electric current, acting as an electrolyte, flows through the droplet and causes the iron ions to dissolve. This forms oxide hydrate, which is most commonly known as rust.

Type of Corrosion

Knowing the differences among the types of corrosion can help you understand how to effectively prevent it from occurring.

Uniform corrosion is the most common type—it has a reddish colour that covers the entire exposed fastener. You can prevent it by choosing the right plating and coating option.

Galvanic corrosion occurs when you have two different metals in the presence of moisture. It’s prevented by using materials that are noble—or at least more noble than the joints.

Crevice corrosion occurs only in the small gaps and recesses of your fasteners that draw moisture and aren’t properly ventilated. It is prevented by making the joint interfaces smooth in order to avoid crevices as well as not using washers if possible. 

Pitting corrosion happens on very noble finishes, such as chromium and nickel, and is prevented by keeping surfaces smooth and clean. Stress corrosion cracking usually starts as pitting corrosion and occurs on fasteners that are subjected to tension. It’s prevented in the same way as pitting corrosion as well as with periodical safety inspections and, often, hot dip galvanizing.

Finally, intergranular corrosion happens when stainless steels are heated at a high temperature, such as during welding and hot forming, and is prevented by quenching the parts in water immediately after heating or using stainless steels with a carbon content below 0.05%.

Preventing Corrosion from the Start

The easiest way to ensure that rust doesn’t ruin your fasteners is to make protection a priority right from the beginning of your design process. Consider what environments they are going to be placed in—will they be in contact with water, rain, or snow? If so, you must ensure that you get the correct level of protection for the type of elements they’ll be exposed to.

Choose the Right Manufacturer

When you choose to work with a manufacturer that has excellent customer service, is knowledgeable when it comes to the different types of corrosion, and has the plating and coating options to suit your needs, you can prevent rust from occurring before it becomes a problem. Your manufacturer should be able to talk you through the different options and help you choose a surface plating or coating that has been put through salt-spray testing and will be best for your application.

What Are the Different Bolt Plating Options?

When you’re tasked with purchasing bolts, you might think it’ll be an easy decision. After all, how many options will you have to choose from? They’re all basically the same thing, with the same purpose, right? Nothing could be further from the truth.

In fact, a lot of factors need to be considered to ensure that you’re choosing the right ones for your specific application. One factor in particular, bolt plating, can make a big difference in the effectiveness, strength, integrity, and longevity of your bolts. Choose the wrong bolt plating option and your fasteners might quickly succumb to corrosion caused by the elements they’re exposed to.  And since corrosion is inevitable when it comes to fasteners, it must be dealt with head on—protection must be a top priority during the manufacturing process.

To get the most out of your bolts—to ensure they work effectively for a long time to come—you must choose a bolt plating option that can properly protect your fasteners from the harsh environment elements. With the right bolt plating your fasteners can stand strong against moisture so they last for the long term, without giving out to rust.

Here are some of the different plating options you’ll need to consider before you begin the design process of your new fasteners.

JS500

If you want an effective and also cost-effective plating option for your bolts, JS500 might be your best bet. This electrolytic zinc coating, with a .0003 inch minimum thickness leached in JS Solution, protects against corrosion but won’t affect the dimensions of your applications. Because it’s so thick, it can cover the majority of the steel blemishes, like gaps and crevices, that pull in moisture and speeds up corrosion.

JS Plus

JS Plus is one of the best bolt plating options on the market right now, and best of all, it won’t break the bank. It can considerably increase your bolts’ longevity by protecting them against even the harshest elements for a long time. In fact, it’s been proven to protect against corrosion for up to 1,500 hours during salt spray testing.

Electroplating/Zinc Coating

Electroplating, which is also commonly known as zinc coating, is a thinner and more aesthetically appealing bolt plating option. It’s applied to fasteners with the use of an electric current. The bolts are first immersed in a zinc-salt solution, and then a current of electricity is applied. This option is ideal for bolts that won’t face extreme elements, such as bolts used indoors. However, it won’t provide the level of protection needed for outdoor applications, because it’s too thin to withstand constant contact with moisture.

Dacromet

If you’re looking for a plating option that can not only offer protection against corrosion but also provide mechanical damage resistance and chemical resistance, then Dacromet might be for you. It’s a water-based, thin, dry film that isn’t electrolytic like zinc plating. It not only boasts passivation and galvanic action, but it’s also self-repairing! You’ll get great protection from the overlapping zinc and aluminum flakes. If you are working on a high-temperature application or you want a plating option that’s paintable, Dacromet will be your best choice.

Talk to Your Manufacturer

Don’t let corrosion ruin the integrity and longevity of your bolts. Fight it with plating. You have many different protection options to choose from and you can find one that is right for your bolts. When you work with a manufacturer that is knowledgeable in corrosion protection, you can talk through the different options and choose one that is best for your application.

5 Common Uses for Rivets

Although bolts, screws, and nails are far more common in the world of fasteners, many applications still require the use of rivets. Rivets consist of a head on one side, a tail on the other, and a smooth cylindrical shaft connecting them. Though they can support tension loads, they’re better suited to supporting shear loads that are perpendicular to their axes. Riveting is ideal in situations where workers cannot access the back of the product, such as with a walls or tubing. With riveting, there’s no need to access the rear end of the joint so this isn’t a problem.

Riveting is often a more cost-effective and superior method of fastening. Rivets are easy to install, and thus, have a lower installation cost, while the unit cost is also often lower. They’re available in a variety of materials, types, and sizes in order to meet the requirements of many applications, and they’re reliable because they’re permanently fastened in order to withstand environmental conditions and even severe vibrations. Riveting was a popular method of fastening in the past but it’s still widely used today when a light weight and high strength are vital to the application. They can fasten wood, metal, and plastic.

Here are five common uses for rivets.

Home Building

If you look around your home, inside and out, you might see some rivets that you’ve never noticed before. They’re probably all around you. They’re widely used in gutter construction because nails aren’t as effective for attaching metal sheets together. Additionally, if you have fiberglass roofing, it’s probably held together with rivets. Window blinds, hanger straps, wind guards, and even doors and windows are often installed by riveting.

Wall and Ceiling Decorations and Signs

Because you only have access to one side of a wall or ceiling, riveting is ideal if you’re looking to permanently attach nameplates, signs, or decorations to them. Ornamental objects, Christmas lanterns, Halloween decorations, framed paintings, photo frames, and just about any other type of décor can be efficiently and easily attached to walls and ceilings with riveting.

Woodworking

Wooden stands and shelves, cabinets, lockers—just about anything made out of wood can be held together effectively with the use of rivets. In fact, it’s often the most superior option. They’re more durable than screws and nails, so they ensure a sturdier finished product, which allows the furniture to be held in place for the long run. Even the hinges used on these products, as well as the drawer pulls, handles, and doorknobs placed on them are often attached by riveting.

Jewellery

Both professional and amateur jewellery makers use riveting as a cold connection technique. It allows them to join metal pieces together without having to resort to soldering or using heat, while also adding depth and texture to their jewellery. With just the most basic metal forming skills, some common tools, and some instructional videos, any jewellery maker can use riveting to make cold connections.

Aircraft

Naturally, an aircraft will have to be made from solid, strong materials. But these heavy-duty materials would fall apart if they weren’t fastened together firmly. Though welding, bolting, and brazing are also used in the construction of an aircraft, riveting is also vital to the process. The end goal is to have the strongest union of the parts that are joined together and riveting is necessary to achieve this. It’s most commonly used to join aluminum alloys together, because aluminum is difficult to solder. Riveting provides neatness and strength, while also allowing for a lighter weight in an aircraft. Plus, during the construction and repair of aircrafts, it’s not always possible to reach the rear end of the structure being fastened, which is where riveting becomes especially useful.

What Is Salt Spray Testing?

When you’re buying fasteners—bolts, nuts, screws, etc.—you want to ensure that they’re high quality and that they’ll last over time. You depend on your fasteners’ durability and resilience. You want them to hold up, no matter which harsh environments they’re placed in or what elements they come in contact with. Rusted fasteners can be dangerous and costly to replace. To provide you with the durability that you require from your fasteners, manufacturers rely on the results of salt spray tests.

What It Is in a Nutshell

Salt spray testing is a method of checking the corrosion resistance of coatings and materials used to manufacture products like fasteners. The surface coatings are used in order to provide a level of protection for the metal underneath it. During salt spray testing, an accelerated corrosive attack is produced in order to better predict how well the coating protects the metal. The purpose of the testing is to evaluate a surface coating’s expected life.

Effectiveness

Salt spray testing is typically used to produce quick comparisons between expected and actual corrosion resistance. In reality, there is only a weak correlation between the coating’s duration in the test and its actual expected life. This is due to the fact that many external factors influence corrosion—it’s not a simple process. This is especially true for materials like hot dip galvanized steel, where drying cycles are an important factor to consider for durability.

For this reason, salt spray testing is most effective when used on samples to determine a pass-or-fail grade and compare it to expectations, typically in a quality audit role or to test for the effectiveness of a particular production process.

Salt spray tests are used on phosphate surfaces, zinc and zinc-alloy plating, electroplated tin, copper, nickel, and chromium, organic coatings, paint coatings, and coatings that aren’t applied electrolytically.

Why Do We Use It?

Salt spray testing has long been the standardized corrosion test method because it’s quick, repeatable, and relatively inexpensive. The first such internationally recognized test dates back to 1939. The ASTMB117 test is still the most popular salt spray test used worldwide today. ASTM B 117 and ISO 9227 tests are also standardized and used today.

How It Works

Salt spray tests are conducted in a closed testing chamber. A saltwater solution is applied to a sample via a spray nozzle. This dense salt water fog is used to imitate a corrosive environment. After a period of time, which is dependent on the corrosion resistance of a product, the appearance of oxides is evaluated. The more resistant a product is, the longer it takes for oxides to appear. Testing periods can take between eight to twenty-hour hours to complete for materials like phosphate steel to 720 hours for zinc-nickel coatings and even 1,000 hours or more for certain zinc flake surface coatings.

Different Types of Salt Spray Testing

A neutral salt spray test (NSS) using a 5 percent NaCl solution is most often used for steel-based materials. This type of solution has a neutral pH level of 6.5 to 7.2. On the other hand, decorative coatings, like anodized aluminum, electroplated copper-nickel, and electroplated copper-nickel-chromium are tested with a solution that includes chemicals like acetic acid (ASS) or acetic acid with copper chloride (CASS). These acidified solutions have a pH between 3.1 and 3.3.

The results of a material or coating’s resistance to corrosion in a salt spray test can help you determine whether or not a particular fastener is durable and resilient enough for your needs.

3 Reasons Why You Should Buy Custom Fasteners

Regardless of the industry you’re in, you know that innovation and originality are vital to future growth. In order to outshine your competitors and increase your profits, you can’t just keep manufacturing the same old stuff that everyone else is producing. Instead, you need to create unique products that will have your customers running to the stores to buy them.

To do this, you need to use custom components within your products. And when it comes to fasteners, there are three reasons why you shouldn’t choose generic and, instead, you should go custom.

Manufacture without Limitations

If you’ve come up with an innovative new product, the last thing you want is to be limited by your fastener manufacturer because he can’t create the parts you need to make your product work. When you buy custom fasteners, your creativity will see no limits.

Whatever type of fastener you need, your supplier will be able to deliver. Whatever you want is what you’ll get—without compromise. When you’re not picking a generic fastener out of a book, you’ll get the material you want, the size you want, the coating you want, and the shape you want, without the hassle. You’ll get the exact right fit and the right quality for your application.

Customer Service You Can Count On

If a manufacturer specializes in creating custom fasteners, you know you can count on great customer service. Customizing fasteners for your unique needs takes effective communication. You’ll have to work together to create the fasteners to your particular specifications. Manufacturers who work in customization know the level of communication that is required and they know that effective customer service is key to getting the job done right.

Lowered Costs that Fit Your Budget

It might seem like custom fasteners will cost you more than their generic counterparts, but the fact is you can lower your costs when you go the custom route. The manufacturing costs might be slightly higher, but you’ll save money and time from getting the right product from the get-go, from the streamlined operations, and from the excellent customer service. 

Think about all of the costs you’ll acquire if your generic fasteners don’t actually fit your application—you’ll have to pay to get new ones, and you’ll have to pay to ship the ill-fitting fasteners back for a refund. Then, you’ll lose out on profits with the unexpected downtime on your own production time while you’re waiting for your new shipment to arrive. When you customize your fasteners from the start, you don’t have to worry about any of those extra costs blowing your budget.

Don’t Take the Easy Route—Go Custom Instead

Settling for standard fasteners is the easier route to take—but it won’t allow you to grow your business with the unique products you want to manufacture and sell in order to stay ahead of the competition. When you buy custom fasteners, you’ll be able to manufacture without limits because your precise needs will be met, each and every time.

You can design your products in any way you want, and your manufacturer will be able to match fasteners that fit your design. You won’t have to change your design configurations to fit your fasteners, and you won’t have to settle for fasteners that don’t quite fit your application. And when you choose custom, you’ll notice improvement in the customer service you receive from your supplier as well as lowered overall costs so you don’t break the bank.

3 Reasons Why Your Agricultural Purchasing Manager Might Need a New Bin Bolt Manufacturer

Your agricultural purchasing manager’s job is to find and work with the best manufacturers—the ones that offer the best services and high-quality manufacturing components, like bin bolts, at the right price.

But finding the right manufacturer is no easy task. You can easily get into a business relationship with one that isn’t ultimately suited to your needs without even realizing it. Or you might be working with a great manufacturer whose performance, customer service, or quality was excellent at first but has unexpectedly started to suffer after years of satisfaction. If either of these two situations rings true with you, it might be time for your agricultural purchasing manager to find a new bin bolt manufacturer.

Here are three reasons why your agricultural purchasing manager might need to make the switch.

Low-Quality Bin Bolts

Although you don’t want to break the bank to purchase the highest-quality bin bolts in the world, you do expect to get quality for the money you’re putting into the purchase. When your bin bolt manufacturer cuts corners to save money, the quality of your bin bolts will suffer.

He’ll use low-grade materials that will weaken the components’ tensile strength, load proof, and yield strength. They won’t be able to hold up to the stresses or pressure being placed on them or the environmental conditions they’re meant to withstand. When it comes to agricultural products, you simply can’t settle for low quality. When your bolts are cheap or poorly made, they won’t be strong and they won’t be durable either. They’ll be quickly damaged by rust, wear, leaks, or pressure, which will destroy the integrity of your bin. You just can’t risk it. If you’re seeing poor quality from your bin bolt manufacturer, it’s time to switch to a new supplier.

Poor Customer Service

Your agricultural purchasing manager knows just how important customer service is to getting things done right. If there’s no proper communication between him and the manufacturer, issues can arise, problems won’t get fixed, questions will go unanswered, and shipments can be late—the list goes on and on. 

From the moment the agricultural purchasing manager asks for a quote, to the time he orders and then ultimately receives his product, he should have no doubts that everything is going smoothly. But this peace of mind and control over the purchase can only occur if there’s proper customer service. The relationship between your agricultural purchasing manager and manufacturer will deteriorate once communication starts to break down, which also means it’s time to find a new supplier—one that understands the need for customer service.

Additional Costs

When you’re dealing with additional costs that weren’t on your original quote, you have a big red flag that it’s time to switch to a more dependable bin bolt manufacturer. Additional costs can be caused by a shady supplier trying to gouge you for more money to see if he can get away with it. Or, they might be incurred because the bin bolts you received didn’t meet your needs—they weren’t designed to your specifications, they were made with cheap, low-grade materials, or they were poorly manufactured—and you had to send them back and get them replaced with what you actually wanted. Or, your shipment was late so your own labour, operational, and inventory costs increased because of it.

Many of these costs could have been avoided if your manufacturer had better customer service skills or if he wasn’t trying to cut corners. In any case, additional costs are also a reason to make the switch to a more reliable bin bolt supplier.

The Benefits Of Thread Repair And The Conditions When It Is Needed

Regardless of how careful you are when you install nuts and bolts, it’s bound to happen: stripped threads. When tightened, bolts create a radial spreading force, and this often leads to cracked, damaged, and stripped bolt holes. Bolts can also be damaged from incorrect fastener size, wrong thread pitch, cross-threading, thread galling, rusting, excessive pull-out force, thread fretting, or even just repeated use. Aluminum is especially notorious for damaged threads, but in reality, all threaded fasteners can strip or experience damage rendering them unusable. All hope isn’t lost though. You can fix the problem by repairing the damaged threads.

High Volume Thread Repair

Depending on your end use, you may be in a situation where you deal with large quantities of fasteners. These fasteners can become damaged through rough handling, container damage, or even by the threads hitting against each other.

In these cases, it is not efficient to repair each bolt individually by hand. Subject to various factors including the type of damage, the plating involved, and the size of the part. It is possible to repair the damage in a cost effective way by hiring a company who maintains the necessary thread repair equipment and can handle large volumes.

While not practical for the average person in their garage, this option is a good one for those who have invested thousands of dollars in a large volume of fasteners.

Reshaping Threads

Instead of cutting new threads on your bolts, you can reshape them to their original condition after removal. This is ideal when your fasteners are only partially stripped. First, you’ll need to find the bolt’s pitch (metric) or thread count (SAE). You can do this with a thread file or thread gauge—hold it against the threads until you find the right match.

Place your bolt in a vise, engage the thread file grooves and then push on it. This will reset your threads enough to be able to screw on a rethreading die. Put some oil on your bolt and then use the rethreading die to restore it to its original condition. A tap is used for female threads and a die is used to create male threads. The process will take a few operations: don’t do it all at once and avoid cross threading. Rotate the rethreading die or tap few times, and then back it up a full turn in order to dislodge debris. Repeat the process until you see solid threads.

Oversize Thread Replacement

One of the simplest and fastest thread repair methods is to drill out only the stripped threads and tap the hole to the next size up. However, using different thread sizes in a bolt hole pattern isn’t ideal—you’ll then need non-standard fasteners and torque specifications. Instead, you could over-size all of the threads, even if you only have one that is stripped, though this takes more time and effort and could weaken your machine or device.

You can also weld-up the existing hole and then drill a new hole. Then, cut new threads with a tap.

Thread Repair Inserts

You also have the option of using inserts to fix your stripped or damaged bolt holes. These inserts provide strength and durability. You use a specific drill size and tap to put oversize threads into the hole. Then tighten the insert into the threaded hole, some inserts rely on special sealing compounds such as loctite to hold it in place and keep it from turning while others are tightened against the bottom of a blind hole. When you use a thread repair kit with inserts, the kit will specify which correct-sized bit to use and will also supply the tap, so you don’t have to guess and risk damaging the insert, fastener, or assembly further.

Which Thread Repair Method to Use?

The method you should use is going to be based on several factors, including the number of fasteners you need repaired, the material type, the design of your work piece, the type of thread damage to be repaired, the pull-out strength required, and the physical access you have to accomplish the repair. It is important to keep in mind that some damage is not repairable given the use the item will be put to. In these cases, the damaged item should be thrown out and replaced.

Fix It and Forget It

Although repairing threads isn’t as difficult as it seems, you don’t have to try taking on the task by yourself. If you don’t know what you’re doing, you risk damaging your parts further. Instead, you can take your stripped bolts to a thread repair professional or repair shop that specialize in repairing the assembly the damage is in who can do the job for you. Your fasteners will come back good as new. When you have stripped, damaged bolts, or threaded holes there’s no reason to waste your money buying new bolts or new components. Just fix them and forget it.

How to Determine Which Grade of Bolt Your Farming Equipment Needs

When people are working with the farming equipment you manufacture, they’re putting it through some rough conditions and terrain. Naturally, this means your farming equipment has to be tough in order to effectively withstand the pressures and loads that are being placed on it. To create strong equipment, you need sturdy components within in. Specifically, the bolts need to be high quality and durable. If they’re not, they can be quickly damaged by rain, heat, stresses, leaks, and rust, rendering your equipment useless.

A bolt’s strength is expressed in terms of its grade. The grade of bolt chosen for your farming equipment needs to coincide with the job the bolt is meant to do. Choose the wrong grade of bolt and you’ll have useless machines that break down quickly. Choose the right grade and you’ll have equipment that your customers can depend on for the long haul.

General Differences of Grades

To determine which grade of bolt your farming equipment needs, you must first understand the different options you have to choose from. There are many different grades to pick from, which are differentiated by the markings on the bolt’s head. These markings provide proof that the bolt meets the strength standards of the Society of Automotive Engineers (SAE) for conventional sized fasteners and the European Community for metric fasteners. These markings are associated with specific tensile strengths, which is the maximum load in tension that a bolt can handle before breaking, and different materials.

Bolts used in most farming equipment should be manufactured with quenched and tempered carbon steel, though stainless steel bolts made from nickel and chromium are also sometimes used. Stainless steel bolts offer better corrosion resistance, but are generally a higher cost to purchase.

Different Options

Now, let’s look at the most common options of bolt grades that you have to choose from. First, you have Grade 2, which are used when there is no structural load required. This type of bolt has no head markings, is made from low or medium carbon steel, and has a proof load of 33,000 to 55,000 psi, minimum yield strength of 36,000 to 57,000 psi, and minimum tensile strength of 60,000 to 74,000 psi. 

Grade 5 bolts have three radial line markings on the head and are made from quenched and tempered medium carbon steel. These have a proof load of 74,000 to 85,000 psi, minimum yield strength of 81,000 to 92,000 psi and minimum tensile strength of 105,000 to 120,000 psi. Most plow bolts are grade 5, although in certain applications, grade 8 can be used.

Grade 8 bolts are significantly stronger, which is why almost all grain bin bolts are made of this grade. They have six radial lines on their heads. They’re made from quenched and tempered medium carbon alloy steel, have a proof load of 120,000 psi, minimum yield strength of 130,000 psi and minimum tensile strength of 150,000 psi.

The Right Grade for Quality

The durability and strength of the bolts you’re placing in your machines are important to the quality of the bolts and the overall usefulness of the farming equipment you manufacture. The bolt’s load resistance, tensile strength, and yield strength are affected by the grade of bolt you choose. Also, always use the proper grade of nut to match your fasteners grade to achieve the full strength of your fastener needs. If you’re unsure, contact the manufacturer of your equipment for the proper grade of fastener to be used. A reputable manufacturer with great customer service can walk you through the different options so you can ensure that you’re choosing the right grade of bolt for your farming products, which will lead to maximum performance.
