Stainless steel bolt kits.

Bolt strength is measured by tensile strength in psi ( pounds per square inch). Grade 5 120,000 psi, grade 8 150,000 psi, 18-8 and 316 stainless steel 70,000 psi, high strength 316 socket head cap screws are 110,000 psi, 17-4 stainless steel 130,000 psi. Stainless steel on stainless steel will indeed gall and weld itself together if anti-seize is not used. But typically not to other metals. Aluminum is nasty since when it corrodes it expands something like 100 times and absolutely locks fasteners up. After working on underwater stuff, I use anti-seize on every threaded connection except critical fasteners such as rod bolts/nuts, head bolts, main bolts.
