Steel structure bolts are high strength bolts, and also kinds of standard parts. Good fastening performance, used in steel structure, engineering, so that the tightening effect. General steel structure, the requirements of steel structure bolt are 8.8 grade or above, there are 10.9 grade, 12.9 grade, all of them are high strength steel structure bolts, sometimes the bolts on steel structure do not need electroplating, use the natural color is OK
Steel structure bolt is mainly used in steel structure engineering to connect the connection point of steel structure steel plate.
Classification of steel structure bolt:
Steel structure bolts are divided into torsion shear high-strength bolts and large hexagon high-strength bolts. Large hexagon high-strength bolts belong to the high-strength level of ordinary screws, while the torsional shear type high-strength bolts are the improved type of large hexagon high-strength bolts, in order to better construction.
