Description

The C2 Deck-Fix 4.5 × 85mm Screw is a high-performance fixing designed for deep timber connections in outdoor projects. With a patented twin-cut tip, it starts quickly, reduces timber splitting, and drives cleanly without the need for pilot holes in most softwoods.

The green organic coating protects against corrosion for up to 1,000 hours salt spray, while the reinforced TX drive head resists shearing under power tools. Ideal for thicker boards or jobs where extra depth and grip are needed, this screw offers exceptional holding strength and a professional finish.

Key Features

  • Green coating – durable corrosion protection for outdoor use
  • Twin-cut point – fast pick-up and reduced splitting
  • TX drive head – reinforced to resist shearing under load
  • Countersunk head with ribs – flush, clean finish
  • Helix shank – clears debris for improved clamping
  • Designed for decking, fencing, framing, and thicker timber joints

Recommended Uses
This 85mm length is ideal for:

  • Fixing thicker decking boards or composite decking
  • Timber joints where deeper penetration is needed
  • Framing work, pergolas, fencing, or external joinery
  • Where 75mm screws aren’t quite enough for strength

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.
