Description

Timco heavy section self-drilling screws are built for fastening metal into heavy section steel up to 12mm thick without the need to pre-drill. The hardened self-drilling point cuts through steel efficiently, helping speed up installation and making them a practical choice for demanding site work.

Designed with a hex head for secure driving and improved torque transfer, these screws are well suited to steel construction, metal framework and general metal-to-metal fixing. The bright zinc finish makes them ideal for internal and dry environments where a strong, cost-effective fixing is required.

These screws are a reliable option when sealing is not needed and a straightforward heavy duty steel fixing is the priority. They are widely used across construction and fabrication work where speed, strength and ease of installation matter.

Key Features:

  • Self-drilling point for fixing into heavy section steel up to 12mm
  • No pre-drilling required in the correct application
  • Hex head for strong drive engagement
  • Bright zinc finish for internal and dry environments
  • Suitable for metal-to-metal fixing and steel construction work
  • Ideal where a sealing washer is not required

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.
