Steel structure bolt is a kind of high-strength bolt, and it is also a kind of standard part. The fastening performance is better, and it is used in steel structure and engineering to make the fastening function. In general steel structure, the required steel structure bolts are all grade 8.8 or above, and there are grades 10.9 and 12.9, all of which are high-strength steel structure bolts. Sometimes the bolts on the steel structure do not need electroplating, and use natural colors. It's OK.


Application

Steel structure bolts are mainly used in steel structure engineering to connect the connection points of steel structure steel plates.

Steel structure bolts are divided into torsion shear type high-strength bolts and large hexagonal high-strength bolts. Large hexagonal high-strength bolts belong to the high-strength grade of ordinary screws, and torsion shear type high-strength bolts are improved types of large hexagonal high-strength bolts for better construction.


Construction Notes

The construction of steel structure bolts must be tightened first and then final tightened. The initial tightening of steel structure bolts requires an impact type electric wrench or torque adjustable electric wrench; and the final tightening of steel structure bolts has strict requirements, and the final tightening of torsion type steel structure bolts must Use torsion shear type electric wrenches, and torque type electric wrenches must be used for final tightening torque type steel structural bolts.

Large hexagonal steel structure bolts consist of a bolt, a nut, and two washers.

The torsion shear steel structure bolt is composed of a bolt, a nut, and a washer.
