DIN933 Hexagonal Bolt

Hexagon bolts are divided into two types: outer hexagon bolts and inner hexagon screws.

According to the force mode of connection, there are ordinary and reaming holes. Bolts for reaming holes should fit the size of the holes and be used when subjected to transverse forces. Hexagonal heads, round heads, square heads, countersunk heads, etc. Bolts made of high strength steel or requiring a large preload can be called high strength bolts. High strength bolts used in ultra-high pressure equipment need to be prestressed to ensure the sealing of containers. The tightening force of square head can be larger, but the size is large. High strength bolts used in ultra-high pressure equipment need to be prestressed to ensure the sealing of containers. The hexagonal head is the most commonly used.

In addition, in order to meet the needs of locking after installation, there are holes in the head and holes in the rod, which can make the bolt not loose when it is vibrated. Grade 12.9 HEX Bolt is a grade of high strength bolt with higher strength. Many customers will also choose Grade 12.9 HEX Bolt because of hardness.
