Nail Screw, also known as expansion nail, is a fastener used for fixing and connecting. It consists of screw and expansion tube. When the nut is tightened, the screw moves outward, and the cone moves through the axial movement of the thread, thereby forming a large positive pressure on the periphery of the expansion tube. This pressure causes friction self-locking between the wall, expansion tube and cone, thereby achieving a fixed effect. If the load has a large vibration, the Nail Screw may loosen or fall off.
