Which areas are applicable to steel structure bolts

Steel structure bolt is a kind of high-strength bolt, and also a standard part. Good fastening performance, used in steel structure engineering, plays a fastening role.

       Steel structure bolts are divided into torsion shear type high-strength bolts and large hexagon head high-strength bolts. The high strength bolt with big hexagon head belongs to the high strength grade of common bolt, while the torsional shear high strength bolt is the improvement of the high strength bolt with big hexagon head. For better construction, the construction of steel structure bolts must be tightened first, and then tightened. For the initial tightening of steel structure bolts, an impact electric wrench or an electric wrench with adjustable torque is required. There are strict requirements for the final tightening of steel structure bolts. The final tightening of torsional shear steel structure bolt must use torsional shear electric wrench, and the final tightening of torsional shear steel structure bolt must use torsional electric wrench.

       The large hexagon structural bolt consists of one bolt, one nut and two washers.

       The torsional shear steel structure bolt consists of a bolt, a nut and a washer.
