Fully Threaded Tap Bolts Overview
Fully Threaded Tap Bolts, also known as Hex Head Tap Bolts, come with a stem that is fully threaded from the base up to the head, and an underhead washer bearing surface. Unlike a tapping screw, tap bolts are designed to be inserted through holes in assembled parts, because these do not have their own mating internal threads and are tightened by torqueing the head. Because of its fully threaded body, this is used in a variety of applications such as in the vehicle repair industry when attaching a motor to a machinery. Also, these can be used with pulley to adjust the belt tension.

Hex Head Bolt Mechanical Property:
Bolts are mechanical parts, specifically cylindrical threaded fasteners with nuts. They consist of a head and a screw (a cylinder with an external thread). In cooperation with a nut, they are used for fastening two parts with holes. This type of connection is referred to as a bolt connection. When the nut is screwed onto the bolt, the two parts can be separated, making the bolt connection a detachable connection.
