5.5x85 Countersunk Wood to Light Section Steel Wing Tip S/D Exterior Screw Bi Metal/Silver Pack 100
Description A premium bi-metal self-drilling wing tip screw designed for fastening timber to light section steel up to 5mm thick without pre-drilling. The wings ream out the timber to prevent binding and snap off upon contact with the steel, allowing the drill point to penetrate and the thread to tap into the metal. The A2 stainless steel body combined with a hardened carbon steel drill tip provides exceptional strength and superior long-term corrosion resistance for demanding external environments.
