recommend taking the body off first for easier access.
Is there a marking on SS to indicate what hardness they are?

Well, I don't know much about stainless hardware but a quick look at the
McMaster Carr catalog shows that grade 2 bolts have a strength of 60,000
PSI, Grade 5 comes in around 105 - 120,000 PSI and grade 8 boasts 150,000
PSI. This is for cap screws (heax head bolts). 316 stainless and 8-18
stainless both show 70,000 PSI strength putting them somewhere above grade
2.
The numbers are a bit better for socket head cap screws. You alloy steel
cap screw lists a strength of 170,000 PSI and the stainless steel shows
100,000 PSI. (For comparison, a nylon cap screw lists 12,000 PSI). The
ultra-coated steel lists 180,000 PSI strength.
The conclusion drawn from this very superficial review is that the 316 and
8-18 stainless steel socket head cap screws are just a little less strong
than a grade 5 hex head cap screw. But these bolt are in shear and nothing
here indicates whether one is better in this mode than the other. Perhaps
the strength numbers are a good indication. If so then the best choice is
the alloy steel socket head cap screw.
Other opinions?
