Bolt is a mechanical part, which consists of a head and a screw (a cylinder with external threads). It is a cylindrical threaded fastener with nuts.
The bolt is matched with the nut, which is used to firmly connect two parts with through holes. This connection form is called bolt connection. Both the nut can be unscrewed from the bolt and the two parts can be separated, so the bolt connection is a detachable connection.
