Products Description

The Hex head screw is a type of screw with a hexagonal head, usually used in fastening situations where large torque is required.The hexagonal head design allows easy tightening or loosening with tools such as a wrench or screwdriver. The hexagonal head provides a larger contact area than other types of screw heads, helping to disperse the pressure generated during tightening and reducing screw head damage.

Usually Hex Head Screw is divided into two kinds: outer hexagon bolt and inner hexagon screw. It also called Hex cap screw or Hex bolt.Hex head screw standards include: DIN ANSI BS GB and so on.

Mechanical properties of Hex head screw: 4.8, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9.

Advantages:

Hex head screw is widely used in the fastener industry at present, compared with slotted head and Philips head, its assembly is not easy to slip teeth, and the torque is higher. Compared with dodecagonal head and multi-tooth head, it has simple structure and low cost. Therefore, the comprehensive price of hexagonal bolts is higher, and it is also the type of bolts used most in automobiles.

Hex head screw also has many other advantages, such as good self-locking, large pre-tightening contact area, large pre-tightening force, wider range of whole thread length, can exist reaming holes, can fix parts position, withstand shear caused by transverse force.
