Propeller bolts are special bolts used in different automotive propellers. They’re usually hi-tensile and tetanized. Propeller bolts do not work for all wood propellers. Also, a hub’s thickness defines the length needed for the prop bolts.

Automotive bolts such as the pop bolt are threaded fasteners, with a head on end. Using these bolts need pre-drilled holes and nuts. Sometimes it may also require a washer to make sure it won’t loosen. The most common types of automotive bolts are hub bolts, head bolts, and u-bolts. Perhaps the most popular of these are the head bolts.

Moving on to the crucial role the bolts play in car’s safety, it is important to note that bolts must be securely fastened. A loose bolt may lead to tragic vehicular accidents. Automotive fasteners are made of different materials such as steel, iron, brass, nickel, and aluminum. Despite the differences in their built, one thing remains the same: they’re all made to withstand extreme environments.
