Description
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.
Features:
- Twin-cut tip – fast start and low insertion torque
- Suitable for timber and thin metal (max. 0.6mm)
- Ribs under the wafer head for improved countersinking
- Silver organic exterior coating – corrosion-resistant (1,500hr tested)
- Hi-low thread for maximum grip and reduced splitting
- Fire classification: A1
- PH (Phillips) drive for easy use
Typical Applications:
- Fixing cement board or tile backer to timber studs
- Suitable for cement boards up to 6mm
- Use in bathrooms, kitchens, wet rooms and external walls
- Internal & external drylining, cladding and board systems

Delivery & Returns
All orders to the UK mainland are free of charge over £85 inc VAT. Orders under £85 inc VAT are charged at £9.95. We aim to dispatch orders placed before 3pm Monday to Friday on the same working day, with delivery to most UK mainland addresses typically taking 1–2 working days.
Some products have a longer delivery lead time, such as 3–4 working days. Where this applies, the expected delivery timeframe will be clearly stated on the individual product page. Orders may be dispatched from more than one location and items within the same order may therefore arrive separately. Please see our full Delivery & Returns Policy for further information.
Returns: Please inspect your goods as soon as reasonably possible after delivery and contact us promptly if anything is damaged, incorrect or appears to be faulty. Prompt notification helps us investigate delivery issues with our couriers and suppliers, but does not affect your statutory rights.
For consumer change-of-mind returns, you are responsible for arranging and paying the cost of returning the goods to us. Some products, including ladders, long-length building materials and other oversized goods, cannot normally be returned using standard postal services. For large, heavy or oversized goods that cannot normally be returned by post, we estimate that return carriage may cost up to £75 (including VAT) within the UK mainland. The actual cost will depend on the size and weight of the goods, the collection location and the carrier or return service used.
Please contact us before returning any goods so that we can provide the correct return address and any applicable return instructions or authorisation requirements. Different provisions apply to business customers and to goods that are faulty, damaged, incorrect or misdescribed. Please see our full Delivery & Returns Policy for full details.
Should you require any assistance, please email us at sales@fastfixingsonline.com, call us on 07920 120644, or complete our contact form. We are open Monday to Friday, 9am–5pm.
