I would suggest
flathead sms 12 x 4" 25ea / $7.50
but I have a couple of questions
why 12's instead of 10's, 12's seem kinda big
also why are you replacing the 16d SS nails? did they rust or has the wood deteriorated?
I suggest you "flood" the holes with waterproofer before & after installation of the screws. It will help reduce water infiltration.
btw I have built several redwood patio covers using these materials & techniques with good success. regards Bob
a 16 penny common diameter is # 10 x 3 1/2" -- to replace a nail with a screw, I need a larger diameter to allow the threads to engage.
nails are fine - holes and back-up adhesive are "bad"
IMHE, things like thomson water seal lubricate and prevent drying one side only, both of which would exacerbate the problem.
background- (actually, it's an engawa rather than a deck - B redwood on 0.6 treated SYpine w/ oversized framing, clear facing, no splices, nail heads lined, etc.)
I'd worry that flathead screws in countersunk holes would split the redwood.
Pan head or round head screws in counterbored holes might be less likely to split the boards. But the counterbored holes would hold rain, unless plugged with caulk or redwood plugs.

Here is one source. The square drive are excellent fasteners. I saw a set of wooden stairs outdoors in Oregon that ran down to the beach from resort hotel. No staining and the hotel was on the coast.
Have you considered silicon bronze screws?
Here is another source of high-quality fasteners.
Jamestown Distributors (a marine hardware supplier in Bristol, RI) lists 18-8 stainless wood screws, Phillips head, #12x4" in their catalog, part # FSSWSFP12X4. I didn't see that size listed on their website, though. Price is $48.62 per hundred. Their phone is 1-800-423-0030, website is
