Self Drilling Screws with EPDM Washer are high-performance fasteners designed for secure installation in metal roofing, cladding, and other sheet metal applications. The integrated EPDM (Ethylene Propylene Diene Monomer) washer provides a watertight seal, preventing leaks and ensuring long-term protection against moisture and weather. Made from premium carbon steel or stainless steel (A2-304 / A4-316), these screws combine corrosion resistance, strength, and durability. The self-drilling tip allows fast installation without pre-drilling, while the washer ensures a tight and reliable seal. Available in multiple head types (hex head, pan head, wafer head) and drive styles (Phillips, Torx, Hex), they are ideal for roofing, industrial, and construction projects.
