Automotive Body Fasteners: Applications & Types
The complexity of cars is invisible from the outside, but the truth is that these powerhouses depend on small components. In fact, one car can contain as many as 30,000 parts. Many of these components are automotive body fasteners that securely connect larger pieces.
The condition of your car's fasteners is essential to its overall health, so paying attention to them is vital. The following guide outlines fastener basics to help you prevent damage to delicate inner workings and extend the life of your car.
What Are the Different Types of Automotive Fasteners?
There are a wide variety of fasteners on the market to account for niche uses. However, you're likely familiar with the three basics:
Bolts are small, thin pieces of threaded metal that securely attach multiple parts when placed through pre-drilled holes. Unlike screws, bolts have a flat end where you can thread the nut, reducing the risk of the bolt coming loose. Washers are thin pieces of metal with a hole in the middle that go between the bolt head and the surface of the first component. This position provides several benefits:
- Protects the surface of the component
- Prevents looseness
- Distributes fastener's load
Some bolts, called flange bolts, have a washer-like addition (the flange) to the head that provides the same benefits as a washer. As a result, you only need the bolt and nut for installation.
While automotive body fasteners are traditionally metal, many manufacturers use plastic when possible. Both materials have benefits, so it's important to research before deciding which works for your needs.
Plastic
Plastic fasteners can be great options as long as their exposure to extreme heat is minimal. You should also note that plastic body fasteners are generally one-use, so you'll need to purchase new ones every time you change out a part.
For many, plastic's benefits outweigh the downsides:
- Lightweight
- Cheaper than metal
- Nonconductive
- Moisture-resistant, leading to a lower risk of corrosion
Metal
Of course, metal fasteners still have their place. Metal stands up better to heat, especially when combined with anti-seize compounds. You can also reuse metal fasteners, saving money in the long run.
When Should You Replace Fasteners?
Even high-quality and well-maintained automotive body fasteners eventually need replacement. Use puts strain on the component, reducing the yield strength over time. That means an increased risk of failure, even if the fastener seems fine upon inspection.
You should never reuse an auto-body fastener under the following circumstances:
- The vehicle was in a collision.
- The fastener endured high heat exposure.
- The location of use is a critical joint.
- The bolt was over-torqued.
You should also never use a new bolt and an old nut together or vice versa. Any fasteners with visible lubricant, paint, or corrosion should go in the bin.
