Basically correct, in terms of the yield/tensile strength they're pretty close to SAE grade 5. Stainless bolts don't carry a grade/class designation, though they are covered by various (confusing) specifications. The commonly available stuff is 18-8 stainless, and min. properties/dimensions are specified by ASME B18.2.1



Negative.
'8.8' is a metric class designation which is roughly equivalent to SAE grade 5 fasteners, and they are available in chrome-plated.
Class 10.9 are roughly equivalent to SAE grade 8, and 12.9 is an even stronger class which doesn't have an equivalent SAE counterpart.

(Sorry to geek-out on ya, but I had to chime in since this crap has been my bread & butter for a while... )

In that application, I'd use 10.9 - but then I don't think I'd use those adjusters in the first place, since I think they're a poor design (even though they look kinda cool).
Yea, I'm gonna use the stock bolts for back stops to totally avoid any future problems when I get the new units next week. I'm not sure what I think to be honest, I admit to jumping a speed bump, allowing the chain to get way loose AND keeping the axle kinda loose... I don't think that the axle could have moved so far if I had it correctly torqued.
