Description

These Timco self drilling screws with EPDM washer are designed for fixing into light section steel while providing a secure and weather-resistant seal. The integrated washer compresses during installation to create a tight seal against the surface.

Featuring a hardened drill point, these screws drill, tap and fix in one action, eliminating the need for pre-drilling. This speeds up installation while ensuring a consistent and reliable fixing.

The bright zinc plated finish offers corrosion resistance for general construction use, while the EPDM washer helps prevent water ingress, making them suitable for external and semi-exposed applications.

Key Features

  • Integrated EPDM washer provides a watertight seal
  • Self drilling point removes the need for pilot holes
  • Designed for light section steel up to 5mm
  • Hex head for strong and controlled installation
  • Zinc plated for corrosion resistance

Typical Applications

  • External metal fixing

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.
