countersunk self drilling screws for metal

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.
