Steel structure bolts are high-strength bolts and also a type of standard component. The fastening performance is relatively good, used in steel structures and engineering to enhance the fastening effect. On general steel structures, the required steel structure bolts are grade 8.8 or above, as well as grade 10.9, 12.9, all of which are high-strength steel structure bolts.
Steel structure 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
