About 3 years back, after seeing a brand new stainless bolt and nut, gall together immediately after the nut was just hand tightened down,...I decided I'd not use any stainless steel bolts or nuts on my project.
I suppose the answer to this for folks who have/do use stainless steel hardware is to use anti seize on everything,..(which if the anti seize remains over the course of things, I suppose is a perfectly good way to go)..
My choice at the time, was to go with either chrome nuts and bolts ( for the smaller stuff 1/4" 5/16" etc),...and grade 8 steel bolts and or original steel nuts (for the larger 3/8" and so on).
I DID HOWEVER USE STAINLESS STEEL WASHERS PRETTY MUCH ACROSS THE BOARD, as they were cheaper and I had it in my mind that they wouldn't be having their cad or zinc plating scratched off when assembled and begin rusting....
Now, I'm wondering about galvanic corrosion possibilities....??
Anyone out there have any experience with using stainless steel washers around these old cast iron and steel parts ??
thanks for the help...
