Introduction and safety of steel structural bolts

Steel structural bolts are a high-strength bolt and a standard part. The fastening performance is better, and it is used for the steel structure and engineering to make the fastening effect. In general steel structure, the required steel structural bolts are all above 8.8, and there are 10.9 and 12.9, all of which are high-strength steel structural bolts. Sometimes the bolts on the steel structure do not need to be electroplated. Just OK.　　

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

Steel structural bolts are divided into torsion-shear high-strength bolts and large hexagonal high-strength bolts. Large hexagonal high-strength bolts are high-strength grades of ordinary screws, while torsional shear-type high-strength bolts are improved of large hexagonal high-strength bolts for better construction.　　　　　　　　

The construction of steel structural bolts must be tightened first and then tightly. The initial tightening steel structural bolts need to use impact electric wrenches or torque adjustable electric wrenches; and the final tight steel structural bolts have strict requirements, and the final tight torsion shear type steel structural bolts must be Torsion-type electric wrenches must be used for torque-type electric wrenches.　

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

Torsional steel bolts consist of a bolt, a nut, and a washer.
