What areas are steel structure bolts suitable for

       Steel structure bolt is a kind of high strength bolt, and also a kind of standard parts. Good fastening performance, used in steel structure, engineering, so that the tightening effect.

       Steel structure bolts are divided into torsion shear type high strength bolts and large hexagon high strength bolts. Large hexagon high strength bolts belong to the 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, and the initial tightening of steel structure bolts requires impact type electric wrench or torque adjustable electric wrench; however, there are strict requirements for final tightening of steel structure bolts,

       The torque type electric wrench must be used for the final tightening of the torsion shear type steel structure bolt, and the torque type electric wrench must be used for the final tightening of the torque type steel structure bolt. The large hexagonal angle steel structure bolt is composed of one bolt, one nut and two washers.
