Tried a nut and bolt shop? Just take one of the screws with you and ask for one longer.
Should be 316 stainless.
316 stainless eh. Are you a steel worker, or are you just nuts about nuts?
Just nuts about nuts and bolts :p
Never in the steel industry but I know a little about marine stuff and what will and won't corrode, though it seems that you can get "staining" on what is *supposed* to be 316. Nothing to worry about unless it starts to look like coffee/flaky.
I believe there are a couple of higher grades but for the price it's really not worth it.
Suni - Do you know if 316 is rust resistant to town/fresh water?
