Product Introduction
The expansion screw is composed of screw and expansion tube. The
tail of the screw is conical: the inner diameter of the cone is
larger than that of the expansion tube. When the nut is tightened,
the screw moves outward. Axial movement through threads. By moving
the cone part, a large positive pressure is formed around the
expansion tube, and the angle of the cone is very small, so that
the wall, the expansion tube and the cone can form friction
self-locking, thus achieving a fixed effect.
