Hardware - only Stainless Steel.  boxes of 50, cheaper than looking for the washer that rolled off the roof. Real large hardware sizes, may come in 5 or 10 packs.
SS hardware has a habit of galling to itself when you torque it down.   Using some anti-size lube will be good when you have to change something later and dont want to break it or your screwdriver

Thanks Mike, great advice. I have to use Stainless Steel over there at a minimum, salt spray gets into everything. After all, that is to be expected since my place is on a small island, and perched right above the ocean. Anti-seize lube and especially NO-OX-ID can be some your best friend in those conditions.

I read up on stainless steel galling recently . Yes put anti-seize on to prevent that . Also if no anti seize then you should go slow on tightening - using the cordless drill or fast ratcheting on nylock nuts will really get them locked up.
