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.

Expanding plastic screw anchors, often referred to as wall anchors, are designed to secure objects by expanding as a screw is driven into them.
