Products / ITW Buildex Teks Weather Screws

ITW Buildex Weather Screws are self-drilling fasteners with a bonded EPDM sealing washer, built for weather-tight sealing of roof and wall penetrations in exterior, high-moisture applications. The vulcanized bond keeps the EPDM washer from separating from the metal backing, the dual-sealing bonded washer prevents leaks, and the Climaseal coating provides corrosion resistance and lower tapping torque. They are offered with hex-washer or pancake heads, in #1 through #5 drill points, in diameters from #9 through 1/4 inch and lengths from 3/4 inch to 8 inches.
