All our 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)

Please keep in mind when choosing the best screw color to match your roofing that differences in computer screens, in sheet metal roofing production and roofing screw production, the color you order and the color of your roofing may vary to some degree

When Installing these screws we recommend using screw-gun with torque control or a depth sensing feature. Impact tools are not recommended.
