Making outdoor furniture for my patio. Some wood will be cedar and some redwood. Should I spring for stainless steel screws or will deck screws that are rated for pressure treated lumber surfice? Thanks

+1 on stainless. Galvanized or hot dipped nails/screws inevitably lead to long black streaks leading down from the screws as the coating fails.

Its been about 11 years since I built decks on three sides of my house and some of the coated to last forever has rusted completely in two. Save yourself some work later in time.

If I'm nailing I just use good quality Spiral Galvanized nails, for screws I use Galvanized for most structural work and SS for highly visible/arcitectual work.

If plated screws are used, even if they don't rust, they will likely cause staining of the wood. Go with Stainless. Plated may be OK for PT wood, but if you're opting for quality woods, why not use stainless. One thing to be aware of if you haven't used stainless before. It is weaker than steel and you can easily twist the heads off the screws if you don't take the time to pre-drill your holes.

I've built a lot of decks and never had an issue with galvanized on REDWOOD. However, cedar is another story. Get ready to take out a mortgage for stainless if choose those. I just read an article in McFeelys catalog about the differences in stainless quality. The #200 (or something like that) (the cheaper ones) will still rust eventually. You (according to the seller) need to go with the high quality SS.

Like Russ said, lower grades of stainless steel will rust fairly rapidly. In fact, ALL stainless steel will eventually rust, it just takes longer. Even decades. I would still use stainless as previously recommended, but I would also counter bore the screws and plug the holes.

McFeely's is a big supplier of screws,but almost every screw they sell comes from China. The rest come from Taiwan. Just in case this determines your supplier.
