Macsim Treated Pine Screws 8g x 57mm C3 Galvanised

When you're fixing into treated pine, the screw has to stand up to the weather long after the job's done. These Macsim 8g x 57mm screws are Class 3 galvanised, so they hold their grip outdoors in decking, fencing, framing and exterior timber without rusting out.

The Type 17 cutting point bites straight into treated pine and hardwood without splitting the timber, and the self-embedding countersunk head pulls itself flush for a clean finish. A full thread and a number 2 Phillips drive mean solid holding power and easy driving.

One honest heads-up. C3 galvanising is built for general outdoor use, not for salt spray. If you're working within about 200 metres of the ocean or around a saltwater pool, step up to 316 marine-grade stainless instead.
