Description

Fibre cement screws for steel are designed to fix fibre cement profile sheets directly to light section steel (up to 5mm thick). They cut through steel without pre-drilling, so installation is quicker and more efficient. As a result, they are ideal for roofing and cladding where speed and reliability matter.

Each screw includes a 25mm BAZ washer with a stainless steel backing and EPDM rubber seal. As you tighten the screw, the washer compresses and creates a watertight seal. This helps prevent leaks and protects the fixing point from moisture. In addition, the exterior coating provides strong corrosion resistance, tested to over 500 hours of salt spray.

Fibre cement screws for steel also feature reaming wings beneath the head. These wings enlarge the hole in the sheet during installation, allowing natural movement and expansion. Because of this, the risk of cracking or sheet damage is reduced. They are commonly used for securing Big 6 roofing sheets and other external applications.

Key Features:

  • Self-drilling No.3 point for steel up to 5mm
  • 25mm BAZ washer (EPDM + stainless steel) included
  • Exterior corrosion-resistant coating (500+ hours salt spray)
  • Wings allow for sheet expansion without damage
  • Hex head for secure installation
  • Suitable for roofing sheets, cladding, and external applications

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.
