Colorful Tek Roofing Self Drilling Screws For Sheet Metal Hex Head Self Drilling Roof Screws With Washers

metal roofing screws use EPDM washers to seal the screw to metal roofing panel to prevent leaking. The EPDM washer is bonded to a galvanized steel washer to prevent sealing issues and to place even pressure on the EPDM washer. Our metal roofing screw EPDM washers hold up well to ozone, ultraviolet radiation, harsh outdoor environmental conditions and temperature extremes. Compared to neoprene washers, the EPDM temperature range of -60 to 350 F is far superior to Neoprene washers which have a much narrower temperature range. (EPDM - synthetic rubber)

Galvanized hex head metal roofing screws are designed specifically to attach metal roofing panels to wood roof substrate. The course thread design provides maximum holding power and ensure a tight fit. Self-sealing neoprene washers on the screws provide a watertight seal at the point of contact metal panel to wood. Self-tapping point eliminates the need for pre-drilling of panels prior to installation.
