resin anchors for concrete

The key feature of long self-drilling screws lies in their unique. Unlike conventional screws, they possess a sharp point and a series of cutting edges that cut through material like a drill bit. This makes them ideal for use in a wide range of materials, from wood to metal, plastic, and even composite materials. Their length, often extending beyond the standard size, enables them to penetrate deeper into substrates, providing superior holding power and structural integrity.

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.

Moreover, the washer can act as a barrier against corrosion, especially in environments where the screw is exposed to harsh elements. It provides an extra layer of protection between the screw and the material, extending the lifespan of the fastening system.
