The main application of steel structure bolt nut is in steel structure engineering project to connect the nodes of steel plate thick steel structure. Better fastening characteristics, used for steel structure and engineering projects, a fastening effect. In the general steel structure, the required steel structure bolts are above 8.8 grade, there are also 10.9,12.9. All of are high-toughness steel structure bolts. Sometimes the bolts on the steel structure do not use the electroplating process, but use the primary color can be.
Steel structure bolts are divided into torsion-shear high strength bolts and large hexagonal head high strength bolts. Large hexagonal high strength bolt belongs to the high toughness level of general screws, torsional shear high strength bolt is an improved version of large hexagonal high strength bolt, in order to better engineering construction.
