For oak I was always told to go for stainless rather than galvanised (idk if it's a US/UK nomenclature thing) as the oak will corrode anything other than stainless, particularly if there's likely to be any water involved. I have also confirmed this through slightly painful experience!

Stainless steel is stainless steel, galvanized steel is steel with a zinc coating. Stainless is much more expensive but also more resistant to corrosion than galvanized, which costs almost the same as normal steel.

Sort of. The tannins in oak will react with iron which is why stainless is recommended. You'll get unsightly black marks on the steel and the oak surrounding it.

TIL! Thanks that's great info. I really only deal with metal, but this could definitely be good to know in the future.
