The TIMCO Heavy Duty Timber Screws Hex Flange Head Exterior Silver – 10 x 100 includes 10 high-performance screws designed as an alternative to traditional coach screws. These heavy duty screws dramatically decrease installation time as they don’t require a pilot hole into most wood types, making them ideal for external applications or where extra strength is required. Featuring a hex head countersunk design with fixed washer, they offer a 50° deep single thread for secure fixing with high pull-out resistance. The patented multi-layer silver corrosion resistant plating withstands 1,000 hours salt spray test, while the single slash point reduces torque and risk of timber splitting. The innovative helix design removes debris and improves clamping performance, certified to BS EN 14592:2008 standards.
