Details
A type of fastener consisting of a head and a screw (a cylindrical body with external threads) that needs to be matched with a nut to securely connect two parts with through holes. This type of connection is called bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
