metal expansion screw

The primary structure of a wedge-type anchor consists of a threaded rod, a nut, a washer, and the wedge itself. The threaded rod, often made from durable materials like steel or stainless steel, is inserted into a pre-drilled hole. As the nut is tightened, the wedge is forced against the inner wall of the hole, causing the anchor to expand. This expansion generates a powerful frictional force that locks the anchor in place, providing exceptional holding power.
