What Is Hex Bolt?

Hexagon bolt: A fastener consisting of a hex head and a screw that will be fitted with a nut to secure 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 bolted connection is a detachable connection.
