Bolts: Mechanical parts, cylindrical threaded fasteners with nuts. A class of fasteners consisting of a head and a screw (a cylinder with an external thread) in conjunction with a nut for fastening two parts with a through hole. This form of connection is called bolt connection. If the nut is removed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
