I purchased some stainless steel 1/16" hex bolt fasteners with #0 stainless steel washers today and hex nuts. I should have asked you all for your opinion first but is it safe to use these for my restorations of straights? The sales guy told me they will not rust but I don't see many people using stainless steel here. It seems to be more nickel/silver and brass. Here's a photo of them. Thanks for your advice.
