A box of 200 high-performance 5.0 x 60mm woodscrews is a heavy-duty timber fastener designed for demanding structural wood-to-wood joinery and site fixing applications. Featuring a double-countersunk head with self-countersinking ribs, a serrated thread pattern, and a sharp cut point, it drives rapidly without pre-drilling or splitting the wood. Treated with a protective low-friction coating for reduced driving torque, the extended 60mm length and robust 5.0mm shank diameter provide superior clamping force, shear strength, and pull-out resistance—making it ideal for securing structural timber studs, heavy joists, floorboards, and exterior timber framing.
