Advantages of Fasteners

Increased Efficiency
One of the primary advantages of fasteners is that they can help to increase efficiency in a variety of applications. Fasteners can be used to quickly and easily connect two or more components, which can save a significant amount of time and effort when compared to traditional methods such as welding or bolting.
Enhanced Safety
Another advantage of fasteners is that they can enhance safety in a variety of applications. For example, fasteners can be used to secure components in place so that they are less likely to become loose or detached, which could potentially lead to accidents.
Improved Aesthetics
In some applications, fasteners can also improve aesthetics. For example, hidden fasteners can be used to create a cleaner and more streamlined look in furniture or cabinetry.
Greater Strength and Durability
Fasteners are also typically stronger and more durable than traditional methods of joining two or more components. This is due to the fact that fasteners are designed to create a tight connection that is resistant to vibration and other forces that could potentially cause traditional methods, such as welding or bolting, to fail.
Reduced Cost
Finally, fasteners can also help to reduce costs in a variety of applications. This is because fasteners are typically much less expensive than traditional methods such as welding or bolting. Additionally, fasteners often require less labor to install, which can further reduce costs.

Types of Fasteners

Threaded Fasteners: Threaded fasteners are easy to install and uninstall. Three types of threaded fasteners are.

Bolts: This type of threaded fastener has a hex head on one end and is threaded on the other end. Bolts are often used with a nut or washer to keep them in place. The bolt is inserted through the two parts you are trying to join before being secured in place by the washer.

Screws: Screws are likely what comes to mind when you think of a fastener. Like bolts, screws also have a hex head on one end and are threaded on the other end. They are different from bolts, as they are screwed into an internally threaded hole for added security. They are one of the most versatile fasteners since they do not require anything extra to hold them into place.

Studs: Studs have no head and are threaded on both ends. They are used to join two other objects with internally threaded holes. Studs are usually meant to provide a permanent attachment and are often welded or bonded.

Non-threaded Fasteners: Non-threaded fasteners are often permanent options. Styles of non-threaded fasteners include.

Nails: Typically made of metal, nails are a common fastener available in many sizes for different applications. You can find individual nails or nails made for air guns.

Rivets: Rivets are strong, permanent non-threaded fasteners with a head, shank and a tail. They bring materials like metal, leather and wood together and can be hand-driven or power-driven.

Pins: Pins come in a wide range of styles, from small pins you would use in sewing to durable, mechanical styles. These fasteners are unthreaded and often headless, and they are usually designed to go into premade holes.

What Are Fastener Grades?

Fastener grades are the markings or numbers found in the head of screws or bolts. These symbols specify a significant purpose that indicates a manufacturing class for each component. There are different types of markings on fasteners such as letters, numbers, dashes, slashes, dots, and others.

The two common grades of fasteners are SAE and Metric. SAE grades on bolts are created by The Society of Automotive Engineers to help identify valuable information about the fasteners using an imperial measurement system. Grades like 2, 5, and 8 and common representations of tensile strength, yield strength, and proof load for SAE-graded fasteners.

ISO or International Standards Organization is a worldwide organization that monitors the quality of fasteners in the market that have created Metric classes or a combination of two numbers separated by a dot. The common examples of metric grades on fasteners are 5.8, 8.8, 10.9, and 12.9, the higher the number is the stronger the material is.

Track Bolts and Nuts for Grade 8.8 10.9 12.9

Different Types Of Coatings Available With Fasteners

Fasteners when exposed to harsh environmental conditions may lose their durability and their corrosion resistance. Coating the fasteners helps avoid these implications and helps improve their performance. There are a variety of coatings commercially available which varies with the variation in types of fasteners, some of which are mentioned below.

Clear and Yellow Zinc

Zinc coatings are inexpensive and therefore the most popular coating. Clear zinc fasteners have high oxidation resistance. Both Clear Zinc and Yellow Zinc coated fasteners are ideal for use in humid environments.

Chrome and Nickel

They both improve corrosion resistance but are used for giving an aesthetic touch to the fasteners.

Grey phosphate

The Grey phosphate-coated fasteners have a better lifespan.

Electro-galvanized

This coating adds thin layers of zinc for protection against corrosion.

Brass and Bronze

Both these metals have high corrosion resistance and are visually appealing, so they are used to add finishing touches to the fasteners.

How Are Fasteners Made?

Cold Forging

This method enables the high-speed manufacture of net shape parts or near net shape parts with favorable mechanical properties and a high-quality surface finish. Another benefit to cold forming over hot forging or machining is work hardening. During cold plastic deformations, the material’s crystal structure undergoes profound changes, becoming stronger and more resistant. The result is a finished part with better physical and mechanical properties. The process does present some limitations, in that parts with bigger diameter need more pressing force to be shaped. Therefore, other methods may be preferable. The performance of cold forming machines depends, among other things, on the size of the fasteners to be manufactured.

Hot forging

Hot forging is the common method for producing bolts with large diameters starting with a thread size of approximately M36 or more, and a length of approximately 300 mm and more. The bar stock is heated up to high temperatures to make the material more malleable and then fed into a forging press. The temperatures are determined by the bar material, geometry, and tolerances. With this process, it is possible to manufacture even complex shapes and high degrees of forming. Hot forging is also the process of choice for manufacturing fasteners made from nickel-based alloys and titanium alloys. A distinctive feature of hot-formed fasteners is their raw surface structure.

Machining

Machining is a manufacturing technique in which a metal is cut into a desired final shape and size by a controlled material-removal process. This method is really only suitable for non-standard fasteners and small quantities, as it generates a great deal of metal swarf, and it is also time-consuming.

How to Choose the Right Fastener?

Material
Engineers should carefully choose what material is ideal for their application. Steel, stainless steel, and thermoplastics are common fastener materials. Each of these materials have different cost and performance characteristics. Engineers have to consider static load force requirements in their application. Choosing a material that cannot withstand the forces during normal operation could lead to failure. Steel and stainless steel provide high to medium load performance. Meanwhile, thermoplastic has a low rating when it comes to load performance. This material choice largely depends on the end application. For example, the access panel must hold firmly onto the frame of the car while experiencing all of the forces and vibrations that occur when a car drives down a road. An all metal system is typically used due to the high strength of the material.

Lifecycle
Engineers have to consider how long the fastener will last in operation. Cycle life performance is dependent on the number of expected times users will fasten and unfasten the device, plus the design and material of the fastener. The operating environment may also impact the cycle life of the fastener. Extreme high or low temperatures and salt corrosion may have detrimental effects on the cycle life expectancy. For example, a car access panel will need to be removed to service the vehicle while performing routine maintenance. The fastener should be able to withstand the user unfastening and fastening the panel. Since the car will have regular maintenance throughout its lifetime, the fastener should be designed to have a cycle life equal to or greater than the expected service life of the vehicle. Southco offers fastener designs for high and moderate cycle lives.

Application Environment
One of the main factors in fastener choice will be the environment that the product will be operating in. Engineers should understand the vibration and shock that the fastener will be exposed to. Other moving parts, dropping the panel, and other operating conditions can vibrate and shock the fastener which can lead to unfastening. For example, a car access panel fastener will be constantly exposed to vibrations from the car operating. Engineers should fully understand the temperature, chemical, and sunlight conditions that the fastener will be exposed to. Fasteners that are exposed to outdoor environments with sun and wind will likely degrade faster than if the product was only exposed to indoor environments. Chemical exposure from materials, such as oils and cleaning chemicals, could compromise the quality of the fastener. A car access panel is often made of plastic to resist outdoor exposure. The fastener will need to withstand the same conditions without corroding.

Security Requirements
Engineers may be designing products that have certain security requirements. Hand operable fasteners are used when there is no need for high security. Engineers can use wing, bail, and knob style fasteners for various low-security needs. These fasteners are designed for maximum ease of use. To improve security some fasteners can only be operated with certain tools. This limits access to the enclosure to users who have the correct tool. Users can incorporate unique tools to increase security. There may be certain regulatory requirements that require products to be designed with this type of fastener. Phillips and Slotted stud recesses are examples of tool-operable fasteners.

What Are the Best Practices for Fastener Installation and Maintenance?

01/

Choose the Right Fastener

The first step is to select the appropriate type, size, material, and grade of fastener for your application. You should consider the load, environment, corrosion, vibration, and temperature factors that affect the fastener performance and durability. You should also consult the manufacturer's specifications and recommendations for the fastener selection and installation.

02/

Prepare the Surface

The second step is to prepare the surface where the fastener will be installed. You should clean, degrease, and remove any dirt, rust, or paint that might interfere with the fastener contact and alignment. You should also check the hole size, shape, and location, and make sure they match the fastener dimensions and tolerance. If necessary, you should drill, tap, or ream the holes to ensure a proper fit.

03/

Install the Fastener

The third step is to install the fastener correctly and securely. You should use the right tools, such as wrenches, drivers, or torque meters, and follow the manufacturer's instructions for the fastener torque, angle, and sequence. You should also use the appropriate washers, nuts, locknuts, or locking devices to prevent the fastener from loosening or falling out. You should avoid over-tightening or under-tightening the fastener, as this can cause damage, stress, or leakage.

04/

Inspect the Fastener

The fourth step is to inspect the fastener after installation and periodically during operation. You should check the fastener for any signs of wear, corrosion, fatigue, or deformation. You should also measure the fastener torque, preload, or elongation to verify that they are within the acceptable range. If you find any defects or deviations, you should replace or repair the fastener as soon as possible.

05/

Maintain the Fastener

The fifth step is to maintain the fastener properly and regularly. You should clean, lubricate, and protect the fastener from moisture, dust, or chemicals that might cause corrosion or deterioration. You should also follow the manufacturer's guidelines for the fastener service life, frequency, and method of maintenance. You should keep a record of the fastener installation, inspection, and maintenance history for future reference.

06/

Follow the Safety Rules

The sixth and final step is to follow the safety rules and precautions when working with fasteners. You should wear protective equipment, such as gloves, goggles, or helmets, and avoid touching or handling hot or sharp fasteners. You should also dispose of the old or damaged fasteners properly and recycle them if possible. You should never reuse or mix different types or grades of fasteners, as this can compromise their strength and reliability.

Ultimate FAQ Guide to Fasteners

Q: Is it fastener or fastening?

A: A fastener (US English) or fastening (UK English) is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.

Q: What is the commonly used fastener?

A: The most common fasteners are snaps, self gripping devices, and hooks and eyes. The fastener used will depend on the garment fabric, the type of garment, the position and type of opening, the amount of stress the fastener will experience, and the effect you want to create.

Q: What is the strongest fastener?

A: Some of the strongest fasteners include high-strength steel bolts, titanium bolts, and aerospace-grade fasteners. Additionally, fasteners like anchor bolts and expansion anchors are designed to provide strong and reliable fastening in concrete and other heavy-duty applications.

Q: What is the most common threaded fastener?

A: Featuring either internal or external screw threads, threaded fasteners are easy to install and equally easy to remove.

Screws. The most common type of threaded fastener is a screw.

Nuts. Another common type of threaded fastener is a nut.

Bolts. The third primary type of threaded fastener is a bolt.

Q: What can I use instead of a bolt?

A: Screws are versatile fasteners used to join two or more materials together. They are available in various types, such as wood screws, machine screws, sheet metal screws, and self-tapping screws, and come in different sizes, materials, and head types.

Q: How do I identify a fastener?

A: Fasteners are identified by four or five attributes; Type, Material, Diameter, Length, and Thread Pitch or Count (machine thread fasteners only). For fasteners where the head usually sits above the surface such as hex bolts and pan head screws, the measurement is from directly under the head to the end of the fastener.

Q: Is stud a fastener?

A: Studs are externally threaded fasteners that typically look like and operate as threaded bars. They're different from screws and bolts in the fact that they don't usually have a head that requires tightening — just continuous threading that can be paired with nuts.

Q: Is thread a fastener?

A: Threaded fasteners are most easily identified by either an external or internal screw thread. All threaded fasteners share a simple but essential function: to fasten objects together and hold components in place.

Q: Is tape a fastener?

A: Many are discovering however that adhesive tapes and films are proven alternatives to these methods, matching and often exceeding traditional fastenings in strength and durability. Furthermore, they provide unique benefits not found in traditional fastening methods, such as sealing, dampening, shielding and insulating.

Q: What is the oldest form of fastener?

A: The earliest recorded history of fastener use was during the third century. Archeological and other evidence shows that this was when metal rivets were first used. This makes a lot of sense, since this was also when metals were used.

Q: What screws pull wood together?

A: Wood screws are sharp-pointed screws for nonstructural, wood-to-wood fastening. Wood screws have coarse threads and an unthreaded shank near the head, which allows the screw to pull the wood pieces tightly together.

Q: What is a special fastener?

A: A specialty fastener is a type of fastener for a specific purpose or application. Specialty fasteners use various materials, including metals, plastics, and composites. Most often, you'll find these in applications where conventional fasteners would not provide the required level of performance or function.

Q: What is the difference between a nut bolt and a fastener?

A: A nut is a component that fits over the end of a bolt and helps it hold objects in place. A bolt is a non-tapered fastener that uses a washer and nut to hold objects together. A screw is a tapered fastener that mates with an existing thread or creates its own thread in a material as it turns.

Q: Is a retainer a fastener?

A: Bolt Retainers (PT Style) are push-on fasteners that keep screws and bolts in place in many applications. Palnut Bolt Retainers have inner teeth that “bite” onto the screw or bolt providing a secure, vibration-free connection.

Q: How do you choose the right fastener for a specific job?

A: To choose the right fastener for a specific job, you will need to consider factors such as the type of material being fastened, the size and shape of the parts being fastened, the amount of weight that will be placed on the fastener, and the environmental conditions the fastener will be exposed to.

Q: What are some common mistakes to avoid when using fasteners?

A: Common mistakes to avoid when using fasteners include using the wrong size or type of fastener, not tightening them enough, overtightening them, and using damaged or worn out fasteners. The removal of permanent fasteners might require substantial force and might damage the connected surfaces. Permanent fasteners are designed to be a long lasting form of secure connection.

Q: What are the lines on a screw called?

A: That's the thread, the spirals that wrap around the internal or external diametrical surface. External threads are called male while internal threads, such as what we see with nuts, are female. Unlike bolts, screws do not use nuts to make connections and require some form of internal threads to sustain a grip. In most cases, screws are self threading or self tapping, meaning they create the threads into the material where they are being placed.

Q: What is the strongest fastener?

Q: What are the 3 best fasteners?

A: The three primary types of mechanical fasteners are screws, bolts, and rivets. Each type has its own unique design and purpose. Screws are threaded fasteners that typically require a complementary nut or pre-tapped hole. Bolts are similar to screws but are usually larger and feature a separate nut to secure the joint.
