The size, technical requirements, test methods, marking methods and technical specifications of the torsion-shear type bolts produced by our company are in accordance with the GB/T 3632-2008 standard for TC Bolts. When assembling high-strength torsion-shear type bolt joints, the side of the nut with the round table should face the chamfered side of the washer; the high-strength torsion-shear type bolt connection for the steel structure is a modified type of the large hexagonal bolt connection of the steel structure. The main advantage is that the construction of the larger hexagon bolt is simple, the required construction space is small, the electric wrench can be used to directly screw off the tail of the plum blossom head, which is safe, simple and quick, and the construction quality is very convenient, no professional or equipment is required, only general The visual inspection confirmed that the plum head has been screwed off to ensure the construction quality.
