Instructions
The working principle of high-strength bolt connection is to intentionally apply a large pre-tension to the bolt, so that the contact surface of the connecting parts will produce extrusion pressure, so that the vertical straight in the direction of the screw has a lot of friction, relying on this friction to transfer the connection shear force. The pre-tension of high-strength bolts is realized by tightening nuts. The bolts connected by high-strength bolts are made of 10.9s or 8.8s quality alloy structural steel after heat treatment. Holes for high-strength bolts shall be drilled into holes.
