Description

These Timco self drilling screws are designed for fast and reliable fixing into light section steel without the need for pre-drilling. Featuring a hardened drill point, they cut through metal and form a secure thread in one smooth action.

As a result, installation is quicker and more consistent, making them ideal for high-volume fixing on site. The hex head design provides strong drive engagement, reducing cam-out and improving control during installation.

Finished with a bright zinc plating, these self drilling screws offer dependable corrosion resistance for internal and low exposure environments. This makes them a cost-effective choice for general construction, drylining, and metal fixing 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.
