TIMCO Twin-Cut Cement Board Screws – 4.2 x 25mm – Wafer Head – Exterior Silver – Timber & Thin Metal

These Timco twin-cut cement board screws are designed for fixing cement-based boards to timber and thin metal (up to 0.6mm thick). The twin-cut point ensures rapid pick-up and reduced torque, making installation quicker and easier in tough board materials such as 6mm tile backer boards.

The wafer head with ribs underneath gives a flush, secure finish, while the hi-low thread ensures maximum grip in both wood and light steel. Coated in a silver organic exterior-grade finish, these screws are corrosion resistant and tested to withstand 1,500 hours in salt spray tests. They also carry a fire classification rating of A1, making them suitable for high-spec jobs.
