A Hex Head Self-Drilling Screw is a fastener with a hexagonal head and a built-in drill point, designed to drill its own hole and tap threads in materials like metal or wood without the need for pre-drilling. The hex head allows for high torque application using a wrench or driver, ensuring secure and efficient installation. ... These screws are commonly made from materials like stainless steel, carbon steel, or zinc-plated steel, offering strength and corrosion resistance. Widely used in construction, roofing, and metal fabrication, hex head self-drilling screws are ideal for quick, reliable fastening in structural and industrial applications.
