expanding hollow wall anchor

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.

Self-tapping screws, as the name suggests, create their own thread while being inserted into a pre-drilled hole, eliminating the need for a separate tapping process. They are particularly advantageous when working with plastic, a material known for its variability in hardness, thickness, and thermal expansion properties. Stainless steel, with its inherent corrosion resistance and high tensile strength, makes an ideal choice for manufacturing self-tapping screws that can withstand harsh environments and maintain a secure grip on plastic substrates.
