What are steel structure bolts

Steel structure bolt is a kind of high strength bolt, and also a kind of standard parts. Steel structure bolt is mainly used in steel structure engineering to connect the connection point of steel structure steel plate.

Steel structure bolts are divided into high strength bolts of torsion shear type and large hexagon high strength bolts. Large hexagon high strength bolts belong to high strength level of ordinary screws, while torsion shear high strength bolts are improved type of large hexagon high strength bolts, in order to better construction、

The construction of steel structure bolts must be first tightened before final tightening. The initial tightening of steel structure bolts requires impact type electric bolts or torque adjustable electric spanners. However, there are strict requirements for final tightening of steel structure bolts, and the final tightening of torque type steel structure bolts must use torque type electric wrench

The large hexagon steel structure bolt is composed of one bolt, one nut and two washers.

The torsion shear type steel structure bolt is composed of a bolt, a nut, a torsion shear type high strength bolt, a large hexagon bolt and a washer.
