Protected by Elementech 2000 surface treatment. Proprietary self-drilling thread. Recessed under-head ribs. CE approved. These ForgeFast decking screws are designed for professional and high-performance outdoor fixing. They are sharp, strong, and corrosion-resistant for up to twice as long as standard alternatives. A super-sharp tip and self-drilling thread eliminate the need for a pilot hole, with the tip biting from the first turn. The deep, TORX-compatible insert ensures reduced cam-out, higher torque, and a firmer drive, minimizing wood splitting. Features recessed ribs for exceptional countersinking and a superior finish. Benefits include: super sharp tip for immediate bite, self-drilling thread to prevent splitting, recessed under-head ribs for superb countersinking, hardened case and core for strength, flexibility up to 35º to prevent shearing, Elementech 2000 surface treatment for extended corrosion resistance, and CE approval.
