Roofing screws in this selection feature a notched type 17 drill point ideal for attaching thin metals 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 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. Like all painted head roofing screws from Albany County Fasteners, Fastgrip type 17 point metal to wood 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 (including unpainted).
