The Sealtite InsulDrill screw is a self drilling, hex washer head metal roofing screw that provides several features to strengthen the metal to wood bond in roofing. The G-90 bonded sealing washer is attached to the fastener, which allows the screw to create a watertight seal to its application. With a #1 drill point, the InsulDrill screw can penetrate 18 gauge steel without pre-drilling and the thread is designed to have excellent holding strength in wood. There is a black e-coat corrosion resistant coating on all screws.
