Hex Head Bolt

The hex head bolt is a type of fastener consisting of two parts, a head and a screw (cylinder with external threads). It needs to be matched with a nut to fasten and connect two parts with through holes. Hex head bolts are divided into two types: external hexagonal bolts and internal hexagonal screws, which are usually used for fastening mechanical equipment.
This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
According to the force mode of the connection, there are ordinary and reamed holes. The hex head bolt used for reaming holes should be matched with the size of the hole and used when subjected to lateral force. According to the shape of the head, there are hex heads, round Head, square head, countersunk head, etc. Generally, countersunk heads are used where the surface after connection is required to be smooth and without protrusions, because the countersunk head can be screwed into the part. The round head can also be screwed into the part. Tightening of the square head The force can be larger, but the size is larger. Hex head bolt is the most commonly used.
In addition, in order to meet the need of locking after installation, there are holes on the head and holes on the rod. These holes can prevent the hex head bolt from loosening when it is vibrated.
