Expanding Expansion Bolt

 

Expanding Expansion Bolt consists of a screw and an expansion tube. The tail of the screw is conical, and the inner diameter of the cone is larger than the inner diameter of the expansion tube. When the nut is tightened, the screw moves outward, and the cone part moves through the axial movement of the thread, thereby forming a large positive pressure on the outer circumferential surface of the expansion tube. In addition, the angle of the cone is very small, causing the wall and expansion tube to Friction self-locking is formed between the cone and the cone to achieve a fixed effect.
