I'd specify stainless screws for hardwood decking. Also good idea to have a non threaded section at least as long as the boards are thick, which allows for movement.
spax screws are good the cheap screwfix ones are a pain the arse on hardwood,
these guys make the best screws IMO
Fantastic screws !.. The trim head makes the screw almost invisible.

TRY WURTH PRODUCTS I HAVE USED THEM FOR YEARS AND THEY ARE QUITE GOOD AT GIVING YOU A DISCOUNT WE USED THEM FOR A LARGE DECKING JOB AT THE WALLACE MONUMENT IN STIRLING TO MENTION ONLY ONE HIGH END JOB THE ALSO GUARANTEE ALL THE SCREWS THEY SELL GOOD LUCK JIM
i normally use stainless for hardwood as well. I gave up using spax as i found them too expensive and they have a tendancy to jack up the wood. Weve been using these for the last couple of years and very impressed. They come with a bit included in eachj box and they will drive through all types of wood without splitting.
Composite deck screws work well on hardwoods as they are pretty tough. They are also colour coated. We supply stainless and carbon steel versions. The stainless are £90/1000 + vat.
The problem with Wurth is they have a tendancy too random price things so you never know how much you are going too be billed after years of frustration we have sacked them .
