Self Drilling Screws with Wings

Self Drilling Screws with Wings are specialized fasteners designed for use with thin metal sheets and composite panels. The integrated wings create a pilot hole slightly larger than the screw diameter, preventing the screw threads from cutting into the sheet before reaching the supporting material. Once the screw reaches the solid substrate, the wings break off, allowing the threads to engage securely. Made from high-quality carbon steel or stainless steel (A2-304 / A4-316), these screws offer excellent strength, corrosion resistance, and reliable holding power. Available in various head types (pan head, hex head, wafer head) and drive options (Phillips, Torx, Hex), they are ideal for applications in roofing, cladding, and metal fabrication.
