Automotive parts manufacturers rely on a variety of connection mechanisms, with fasteners being the primary application. Automotive fasteners are tools such as bolts, washers, nuts, etc. that are used to connect different parts during the manufacturing process of auto parts. They mechanically hold car parts together for secure positioning.

A broad definition of fasteners divides them into permanent and temporary types. Generally speaking, all automotive fasteners, except rivets, are temporary. This means one should be able to remove the fasteners and separate the parts from each other without causing damage.

In addition, the function of automotive fasteners should not be confused with adhesives and glues. Automotive fasteners are different because they use tension to connect car parts. As a result, the vehicle remains intact during stressful situations (even accidents) or after high-speed bumps.
