M4.2–M6.3 410 Stainless Steel External Hexagon Flange Head Self-Tapping Screw with PVC Washer
410 stainless steel external hexagon flange head self-tapping screws with integrated PVC sealing washer for weatherproof sheet metal, roofing, and cladding fastening. The PVC washer compresses against the sheet metal surface when tightened, creating a watertight seal around the screw hole. 410 martensitic stainless steel provides corrosion resistance for outdoor and roofing applications.
