#14 x 7/8" Metal to Metal Type #1 STITCH TEK Roofing Screws
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)
