Description

These are TIMCO's C2 Deck-Fix green decking screws, the everyday choice for building a timber deck. The green multi-layer coating handles over 1,000 hours of salt spray, so the fixings hold up outdoors, and the C2 twin-cut point starts fast, countersinks cleanly and clamps the board down to the joist. The TX drive resists cam-out under a driver. A dependable screw for softwood and most decking boards.

Key Features & Benefits

  • Patented C2 twin-cut point. Rapid pick-up, cuts cleanly and reduces splitting near board ends.
  • Hardened steel core. Takes the torque from an impact driver without snapping.
  • Impact-rated countersunk head. Strengthened to resist shearing, with ribs under the head for a clean, flush countersink.
  • Helix shank. Clears timber debris as it drives and improves clamping between board and joist.
  • Exterior green organic finish. Corrosion rated 3 and tested to 1,000 hours in a salt spray cabinet.
  • TX20 drive. Positive grip with far less cam-out, and a TX20 25mm bit is included in the box.
  • 40 degree single deep thread, partially threaded. The unthreaded shank pulls the board hard against the joist.

FAQs

Can I use these decking screws with an impact driver?

Yes. The head is strengthened to resist shearing when driven with an impact tool, and the hardened steel core handles the torque. Use the included TX20 25mm bit and let the twin-cut point do the work. Ease off the trigger as the head reaches the timber so it countersinks flush rather than sinking too deep.

Do I need to pre-drill before fitting?

For most softwood decking you do not. The C2 twin-cut point cuts its own path and cuts down on splitting, so you can drive straight in. Near board ends, close to a knot, or in dense hardwood, a small pilot hole is still worth it to keep the timber from splitting.

Are these screws suitable for hardwood decking as well as softwood?

They work in both. Softwood boards usually take the screw with no pilot hole. Dense hardwoods such as ipe or balau are tougher, so pre-drill and clear the recess first for a clean, flush finish. The hardened steel and twin-cut point give you the bite you need in harder timber.

Will the green finish fade or rust outside?

The exterior green organic coating is built for outdoor use. It carries a corrosion rating of 3 and passes 1,000 hours in a salt spray cabinet, so it holds up in normal UK garden conditions. The green tone also blends in well with treated softwood decking once the boards weather.

What size and drive are these screws?

This is the 4.5mm diameter C2 Deck-Fix in a TX20 drive, available in several lengths to suit board and joist thickness. Each pack includes a TX20 25mm bit so you can start straight away.

Do they meet a recognised standard?

Yes. The C2 Deck-Fix is manufactured to BS EN 14592:2008, the standard for dowel-type timber fasteners. That gives you a documented fixing for structural outdoor timber work.
