Stitching Screws

Stitching screws are a type of self-drilling screw specifically designed for fastening thin-gauge sheet metal to other metal sheets, such as in roofing, cladding, and fabrication. They feature a fine thread and a drill point that efficiently cuts through the material, followed by threads that secure the sheets tightly together. Most variants include an integrated washer, often with a bonded EPDM seal, to provide a weatherproof and vibration-resistant fixing.
