Designed specifically for securing cement boards to timber and thin sheet metal (up to 0.6mm), these screws ensure a secure and flush finish with a self-countersinking head. The twin-cut point and hi-low thread provide rapid “pick-up” and reduced torque, making them ideal for 6mm tile cement boards. Featuring an exterior-grade organic coating, they offer superior corrosion resistance in damp or corrosive environments compared to standard fasteners. Ribs under the head enhance countersinking for a clean, professional finish. Tested to withstand 1,500 hours in a salt spray test, these screws deliver exceptional durability, and their A1 fire classification ensures compliance with stringent safety standards.
