bolt expansion anchor

The process begins with drilling a hole into the substrate to the required depth. The bolt is then inserted into the hole, followed by the introduction of the chemical compound. This mixture, usually composed of a resin and a hardener, reacts when combined, expanding and filling the space around the bolt. As the mixture cures, it forms a strong, rigid bond that not only secures the bolt but also distributes the load evenly, enhancing structural integrity.

Self-drilling framing screws are typically made from high-strength materials such as carbon steel or stainless steel, ensuring durability and resistance to corrosion. One of the most distinctive features of these screws is their unique tip design, which includes a sharp, drill-like point. This point enables the screw to penetrate the material and create its own pilot hole as it is driven in, making it ideal for use in wood, metal, and composite materials.
