The Stitching Screw is a specialized fastener designed for “lapping” or joining two thin metal sheets together rather than securing a panel to a heavy structural frame. Built from high-strength Carburized steel, these screws feature a unique thread profile and a Flat Ring washer designed to create a weather-tight seal on the surface of the panel. They are the primary solution for ensuring the “stitching” of side laps in roofing and wall cladding stays secure and leak-free.
