The TIMCO Heavy Duty Timber Screws are designed as an alternative to traditional coach screws, dramatically decreasing installation time as they don’t require a pilot hole into most wood types. These screws are ideal for external applications or where extra strength is required, featuring a hex head countersunk with fixed washer design. Coated with a patented multi-layer corrosion resistant silver plating that withstands 1,000 hours salt spray test, they offer superior durability. The 50° deep single thread provides secure fixing with high pull-out resistance, while the single slash point reduces torque and risk of timber splitting. The innovative helix design removes debris and helps improve clamping performance.
