Automotive fasteners are used in the manufacturing and assembly of vehicles. They come in different types and sizes, and each serves a specific purpose. Here are 11 different types of automotive fasteners:
- Bolts and Nuts: Bolts and nuts are used to join two or more parts together. They come in different sizes and are available in various materials, including stainless steel, carbon steel, and aluminum.
- Screws: Screws are similar to bolts but have a tapered shank and are threaded all the way to the head. They are used to hold two parts together, and their threads provide a strong grip.
- Washers: Washers are used to distribute the load of a fastener over a larger area. They help prevent damage to the surface of the material being fastened.
- Rivets: Rivets are used to fasten two or more pieces of metal together. They are commonly used in automotive manufacturing because they are strong and durable.
- Pins: Pins are used to secure parts in place. They can be made from various materials, including steel and brass.
- Clips: Clips are used to hold two parts together. They are commonly used in automotive interiors and exteriors to secure panels, moldings, and trim.
- Retainers: Retainers are used to hold parts in place. They are commonly used in automotive engine compartments to secure hoses and wiring.
- Grommets: Grommets are used to protect wiring and hoses from sharp edges. They are commonly used in automotive manufacturing to protect the wiring harness and other components.
- Springs: Springs are used to provide tension and compression in various automotive components, including brakes, suspension, and steering systems.
- Anchors: Anchors are used to secure parts to a fixed location. They are commonly used in automotive interiors and exteriors to secure panels, moldings, and trim.
- Welding: Welding is a process of joining two pieces of metal together by heating them to their melting point and fusing them together. It is commonly used in automotive manufacturing to join various components together.
What are the different types of automotive fasteners?
There are different types of automotive fasteners based on their make-up materials and intended functions. The most common classification is based on materials, which can either be metals or plastics. Metal automotive fasteners are generally made from iron, aluminum alloy, and copper, while plastic automotive fasteners are made from materials such as vinyl and rubber.
The common types of automotive fasteners are nuts, bolts, and screws. Nuts are small metal components made using iron or aluminum alloys, and they have spiral cut threading running through their centers. Bolts are fasteners with long, partially-threaded shafts with non-tapered ends. They are used to hold automotive parts such as engine components, dashboards, and suspension arms. Screws are fasteners with completely tapered shafts that hold two parts together, and they can cut their threads in a hole or mate with a threaded hole in a part.
Other types of automotive fasteners include self-clinching fasteners, riveting fasteners, and blind threaded inserts. Self-clinching fasteners are one-time and permanent fasteners used to join automotive sheet parts, while riveting fasteners are used to achieve permanent part assembly. Blind threaded inserts are used to create a threaded hole in a non-threaded material.
Fasteners are essential components in automotive part manufacturing. They play a vital role in the assembly and functioning of automotive parts. However, choosing the right type of fastener is critical, as the wrong pair of fasteners can severely impact the vehicle’s performance or lead to damage to the parts. Therefore, proper tightening of the fastener is equally important in ensuring its proper functioning. This article discusses the different types of fasteners used in the automotive industry, the importance of proper tightening of fasteners, and ways to eliminate the risks of loose fasteners.
Specialty fasteners are one type of fastener used in the automotive industry. They have a special design that makes them applicable to certain industries, materials, and applications. They are used when the part manufacturer needs a special design due to their uniqueness in shape, material composition, or application. Before using a specialty fastener, testing is necessary to ensure that it performs well. For instance, SI® inserts are special fasteners applicable in joining plastic parts that require strong and permanent threading. They are also applicable when the unit requires frequent assembly and disassembly.
Another type of fastener used in the automotive industry is surface mount fasteners. These fasteners use the surface mount technology that involves adhering the fastener directly onto the solder pad on the printed circuit board surface. The surface mount technology removes damage to automotive parts during installation, improves assembly speed, and reduces scrap/waste.
Broaching fasteners are also used in the automotive industry. They are available in stud, nut, standoff, etc., pressed and attached to non-ductile materials or ductile materials with a maximum hardness of aluminum. They have a simple installation and are applicable when the surface mounting is unsuitable.
The importance of proper tightening of automotive fasteners cannot be overemphasized. Improper tightening in the engine can cause bolts to loosen, preventing the car from starting. In addition, improper tightening of fasteners in the brakes of vehicles can increase the chance of accidents. Therefore, choosing the right fastener is critical, as the wrong pair of fasteners can severely impact the vehicle’s performance or lead to damage to the parts.

Eliminating the risks of loose automotive fasteners is crucial in ensuring the proper functioning of the vehicle. There are several ways to eliminate the risks of loose automotive fasteners. Choosing robust material is the first step. The choice of material plays a huge role in the properties and application of the automotive fastener. As a result, you should ensure you choose a sturdy material with the needed properties to hold the two automotive parts together effectively. For example, automotive fasteners made from iron, aluminum, and other metals are strong and durable. However, plastic automotive fasteners such as vinyl have less durability but are more replaceable.
Doing some assessment beforehand is also important. Assessing the purpose of the fastener would allow you to reduce labor and repair costs. You should ensure that the material properties match the application of the fastener. For instance, it would be a waste of capital to use metal automotive fasteners in replaceable parts.
