Hex Head Tek Screw With Integral Washer, Coated
Hex head self drilling screws are fasteners that have a drill point which enables users to drill them directly into material without having to pre-drill a hole. Integral EPDM washer installed into the head provides a consistent weather-tight seal. As the washer is integral to the head, these screws are superior to screws with a separate washer since they eliminate corrosion due to moisture getting in between the head and the top of the washer. In addition to the standard drill points, some sizes are available in a stitch point for lap joints in metal roofing. These fasteners are available with a long life coating.
