Bolt

Steel structure torsion shear bolt is a high-strength bolt and also a type of standard component. Steel structural bolts are divided into torsion shear high-strength bolts and large hexagonal high-strength bolts. Large hexagonal high-strength bolts belong to the high-strength grade of ordinary screws, while torsion shear high-strength bolts are an improved type of large hexagonal high-strength bolts for better construction. The large hexagonal steel structural bolt consists of one bolt, one nut, and two washers. Twist shear steel structural bolts consist of one bolt, one nut, and one washer. On general steel structures, the required steel structural bolts are grade 8.8 or above, as well as grades 10.9 and 12.9, all of which are high-strength steel structural bolts. Sometimes, bolts on steel structures do not require electroplating.
