Automotive Fasteners, Gaskets & Accessories

What are three types of automotive fasteners?

Automotive fasteners play a critical role in the construction, repair, and maintenance of vehicles. There are numerous types of automotive fasteners, but here are three common categories:

1. **Bolts:** Bolts are threaded fasteners that require a nut to secure two or more components together. Automotive bolts come in various lengths, diameters, and thread pitches to accommodate different applications. Common types include hex bolts, flange bolts, and carriage bolts.

2. **Screws:** Screws are similar to bolts but typically do not require a separate nut. They are self-threading and can be used to secure components together or to attach items to vehicle surfaces. Sheet metal screws and self-tapping screws are examples of automotive screws.

3. **Nuts and Washers:** Nuts are paired with bolts or threaded studs to create a secure connection. Washers are often used with nuts and bolts to distribute pressure and prevent damage to surfaces. Lock nuts, wing nuts, and hex nuts are commonly used in automotive applications.

What are the common automotive fastener sizes?

Automotive fasteners come in various sizes to accommodate different applications. Common fastener sizes are typically measured in terms of diameter and thread pitch for bolts and screws. Here are some standard sizes you may encounter:

- **Bolt and Screw Diameters:** Common automotive bolt and screw diameters include 1/4-inch, 5/16-inch, 3/8-inch, 7/16-inch, and 1/2-inch. These measurements refer to the diameter of the fastener's shank.

- **Thread Pitch:** Thread pitch indicates how fine or coarse the threads are on the fastener. For example, you might encounter thread pitches like 16 threads per inch (TPI), 18 TPI, or 20 TPI.

- **Nut Sizes:** Nuts are typically sized to match the corresponding bolt diameter. For instance, a 3/8-inch bolt would require a 3/8-inch nut.

How much do automotive fasteners cost on average?

The cost of automotive fasteners can vary widely depending on factors such as type, size, material, and quantity. Here's a general idea of what you can expect:

- **Individual Fasteners:** Single automotive fasteners can cost as little as a few cents to a few dollars each, depending on the type and size.

- **Assortment Kits:** Assortment kits containing a variety of fasteners are available and can cost anywhere from $10 to $50 or more, depending on the size and quality of the kit.

- **Bulk Purchases:** Buying fasteners in bulk quantities can lead to cost savings. For larger quantities, the price per unit can be significantly lower.
