Heavy Hex Bolt: A type of fastener consisting of a head and a screw (a cylinder with an external thread) that is to be fitted with a nut for fastening two parts with through holes.

This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
