M8 M10 12.9 High Strength carbon steel High strength bolt

Description

The high-strength bolt is made of high-strength steel and requires a large pre tightening force. There are several categories as follows.

Friction type is applicable to beam and column connection, solid web beam connection and factory heavy lifting beam connection

Pressure bearing high-strength bolts are suitable for shear connections of static load structures that allow less sliding.

When the tensile bolt is in tension, its fatigue strength is relatively low, so it can only be used for flange butt joint of pressure bar.
