McFeelys.com or their catalog has a LOT of information on screws. I'd
try looking there and maybe emailing them direct if you can't find what
you need. And folks here are a wealth of knowledge, so post more
detail on your application and you'll most likely find what you're
looking for. (My tip: drill accurately sized pilot holes!)

I've done the same thing. I use 1x2 pine (or similar available scraps)
for the supports that run perpendicular to the joists. I use one #8 x
2" screw at each intersection. Place a cross piece every four or five
feet. Do use the square drive screws from McFeelys. The difference is
amazing.

I always try to stagger fastenings rather than put them in a straight line.

Quantity depends on how much weight they are holding and how that weight
acts on them...if the weight is trying to shear them you need very few
compared to pull out weight.

Best I can offer with info given...
