Needle Point Hex Head screw with EPDM sealing washer for fixing thin steel or brackets to thin steel sections where a large hex head and waterproof characteristics are required. The needle point tip aids in piercing the surface material, eliminating the need for pre-drilling (please see screw self drilling capacities) and saving time during install. The flanged hex head provides for easy installation and comes in a class 4 galvanised finish, making it ideal for internal and external applications.
