FastGrip Hi-Lo thread mini driller roofing screws feature a mini driller self drilling point to attach metal roofing and siding to wood with ease. They are made of 1022 carbon steel for superior performance and feature a mechanical galvanized zinc plating for durability and corrosion resistance. Fastgrip mini driller hex washer head roofing screws have a strong "V-Neck" head to completely cover the inner diameter of the EPDM bonded washer for a high installation strength and a better seal. Roofing screws in this selection feature a unique Hi-Lo thread style for easy drilling, better holding power, and snug and precise fit. The self-drilling point adds to the benefits of standard Fastgrip roofing screws by making easy work of drilling through metal panels allowing for a faster start time and overall installation. Fastgrip Hi-Lo Thread Type 17 point roofing screws are wet painted. This process creates a long-lasting paint application that stays on and keeps its color. Painted roofing screws are available in 13 different color varieties.
