Description

These Timco self-drilling cement board screws are specifically designed for fixing cement board to steel drylining frames up to 3.0mm thick. Ideal for both internal and external applications, they offer fast installation with no pilot hole needed.

The self-drilling point and self-tapping thread ensure a strong and reliable fix into light gauge steel. The countersunk wafer head features ribs under the head for a flush, clean finish, reducing the risk of board damage.

Finished in an exterior-grade silver organic coating, these screws provide superior corrosion resistance, tested to withstand up to 1,500 hours in a salt spray test. Fire classification rated A1 for compliance on commercial and domestic projects.

Features:

  • Self-drilling point – no pilot hole needed (for steel up to 3.0mm)
  • Self-tapping thread – fast drive and firm hold in metal studs
  • Ribs under wafer head – improves countersinking and prevents board damage
  • Silver organic coating – corrosion-resistant (1,500hr salt spray tested)
  • Fire classification: A1
  • PH (Phillips) drive for easy installation

Typical Applications:

  • Fixing cement board to light steel frames
  • Bathrooms, kitchens, wet rooms and external cladding
  • Tile backer boards and fibre cement boards
  • Suitable for commercial and domestic drylining

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.
