What Stainless Steel grade should I use for my Deck Screws?

The Australian Stainless Steel Development Association recommends using 316 Grade Stainless Steel within 5 km of the Coast. Grade 304 is suitable for most non-coastal environments but is more likely to undergo tea-staining in coastal situations where 316 stainless deck screws should be used.

How do I stop my Deck Screws from rusting?

Firstly, make sure your decking screws are stainless steel and of a suitable grade and finish. For fittings and fasteners on the exterior of houses near the coast this would mean stainless steel grade 316.

Stainless steel should be cleaned and maintained and allow rain to wash down the deck if possible. Stainless screws in treated timber offer superior corrosion resistance and outlasts galvanized steel nails.

See more details on which stainless screw to use and where on the Stainless Steel Decking Screw Flyer.

NB: Always select which grade of stainless steel is appropriate for the application and be sure to follow good stainless steel guidelines. For help and advice on stainless steel grade selection, please contact the Nickel Institute or the Australian Stainless Steel Development Association.
