The core of a chemical anchor lies in its two primary components the resin and the hardener. The resin, typically epoxy or methacrylate-based, is a liquid polymer that, when combined with the hardener, initiates a chemical reaction, leading to the formation of a solid, robust structure. The hardener, often a catalyst, accelerates this polymerization process, turning the liquid mixture into a rigid material capable of withstanding immense loads.

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.
