What is the difference between large hexagonal high-strength bolts and torsion shear high-strength bolts

What is the difference between large hexagonal high-strength bolts and torsion shear high-strength bolts

1. Their appearance is different. The large hexagonal head is hexagonal in shape. The torsion shear type head is semi circular, and there is also a plum blossom head at the end of the bolt.

2. The installation method is different. Install the large hexagon with a torque wrench. During the installation process, the torsion shear type is controlled by the plum blossom head at the tail, and the bolt is tightened in reverse using the reaction force of the torque until the straight toothed end of the bolt is broken

The supporting facilities are different. Each set of large hexagon is equipped with one bolt, one nut, and two flat washers. The torsion shear type consists of a bolt, a nut, and a flat washer.

The company's main products include high-strength bolts, high-strength nuts, steel structural bolts, steel structural nuts, grid sealing plates, grid bolts, etc.
