10 x 1-1/2" GALLERY BLUE Metal Roofing Screws - Hex Washer Head- Self-starting/tapping - EPDM washer

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)

ONLY screw head is painted to ensure EPDM washer seals to metal roof. NO paint on the threads to maximize holding strength.
