The bolt is a Machine element. It is a cylindrical threaded fastener equipped with a nut. It is a kind of fastener composed of head and Screw (cylinder with external thread). It needs to be matched with the nut to fasten and connect two parts with through holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection
