Metal Panel Screws are a specialized product that include a gasket to seal around the screw head and prevent moisture from penetrating the roof or siding through the screw hole, and a screw tip that cuts through the metal panels and is self-starting. Metal panel screws often come in painted colors to match the metal panels. The screws are used to attach metal panels to purlins or sheathing for a metal roof or to girts or sheathing for metal siding. Metal Panel Screws are typically used with a density of 75 screws per 100 square feet of metal roofing or siding area.
