I've heard of crevice corrosion and stress corrosion cracking, but
the third one, chloride stress corrosion cracking, I had not heard

onboard the boat. At least I hope not!


Well, whatever it was, that screw mess it up for the whole bunch.
They ALL are getting pulled and replaced!

Stainless does okay in fresh salt water, but not in stagnant salt
water. The stagnant salt water does not have oxygen which is
essential to keep the stainless with an oxide layer. I am no expert
but you might consider Monel bolts.

Absolutely true. the process is called passivating and can occur only
with the presence of oxygen. Monel sounds good, but its gets
expensive. but anyone with a big boat must have a lot of money
