square head self drilling screw

Long tek screws, also known as 'decking screws' or 'structural screws,' are engineered to provide superior holding power and resistance against various environmental factors. Their length, which exceeds that of standard screws, enables them to penetrate deeply into materials, creating a robust and secure connection. This makes them ideal for tasks requiring substantial load-bearing capacity, such as in construction, woodworking, and machinery assembly.

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.

The hallmark of self-drilling screws is their ability to create their own pilot holes, negating the need for pre-drilling, which can save significant time and effort during installation. The 13mm self-drilling screw is typically constructed from high-strength steel, ensuring durability and reliability. These screws often feature a sharp, drill-point tip which enables them to penetrate various materials quickly and efficiently. Coupled with a robust thread design, they provide excellent holding power, making them ideal for fastening metal, wood, and other materials.
