For anyone who lives or rides close enough to the shore that moist salt air can be a factor, there are different alloys of "Stainless Steel." Avoid the ones that attract a magnet. They're okay for inland riders, but they have enough iron in them that they will rust and generate galvanic corrosion when you throw a little salt into the mix.
Ah...ship talk here! Do we need Anodes? Or one of them galvanic protection systems they now sell for cars? There is a good story up here where they installed one on a ship, connected it wrong and it ate the hull, left the rust behind!
But salt.....lots up here on the roads in the winter, the residue stays on the road way into late spring, I often see the deer licking the cracks where it has accumulated.That is how I figured out them deer whistles didn't work. Inland for sure....I stay away from that "Wet Ocean Weather" when I am not at work.
The flanges for the exhaust manifold on my bike are magnetic stainless, the rest of the system is non magnetic, lots of corrosion on the flanges, took me a couple hours of Dremel work to clean them up.
The good Stainless bolts should be rated A2 (18 8), worth taking a magnet with you when you go buy them,most hardware stores don't know what they sell and bolt markings are often cryptic unless you have the specs.
But ship talk again, I work for a very wasteful outfit, just last week I dove into the metal recycling container and got about 5-6 pounds of SS bolts, washers and nuts....all like new, their loss, my gain!
Here, I'll post what I have on SS fasteners, may be interesting to someone.
