PRODUCT COMPATIBILTY GUIDE: ***Insert_Chart_2***Depending on the application and personal preference, No Paint/Galvanized Zinc screws go well with many types of gray, galvanized and other colors of roofing sheet metal. Generally buying galvanized coated screws is a great way to purchase a long lasting but low cost roofing screw

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)

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