Timco Heavy Duty Timber Screws Hex Flange Head Exterior Silver 8.0 x 40

The TIMCO Heavy Duty Timber Screw combines a hex flange head with a robust design optimized for external applications requiring extra strength and durability. Engineered as an effective alternative to traditional coach screws, this screw is built to withstand demanding environments while offering faster installation in many wood types, often not requiring a pilot hole. Its 8.0 x 40 mm size and heavy duty steel construction provide reliable performance where high pull-out resistance is needed. The finish features patented multi-layer corrosion resistant plating designed to endure prolonged exposure, including salt spray conditions. Additional design details include a hex head countersunk with a fixed washer, a 50° deep single thread to improve clamping and reduce timber damage, a single slash point to lower torque, and a helix that helps remove debris during driving. This combination makes it suitable for external projects or any scenario demanding extra integrity and long-lasting hold.
