Roof sheet fixing screws are designed specifically for fastening metal roof sheets, plastic sheets, and other roofing materials to beams or purlins. They come in various types, including self-drilling screws, which eliminate the need for pre-drilling and enhance efficiency during installation. The design of these screws typically includes a sharp point that easily penetrates metal, along with a hex head for better torque application. Additionally, they often feature rubber washers that provide a watertight seal, preventing leaks and improving the longevity of the roof.
