Can only tell you what people that sell bolts publish:

That thing is misleading…

aside from grade 8 - grade 10.9 is missing (those are the only two that really matter ) and you have stainless steel on it… (for the little non-essential Mickey Mouse stuff I use stainless steel, just because it looks pretty, but for stuff that really has to hold up, I won’t)

the rest of it is chewing gum…  common sense has to be Applied as well..

if you have a M12 with threads in aluminum it doesn’t mean you go by what is published for to specs on M12….  It just means that the manufacture uses a larger diameter with more threaded area to hold in the aluminum.. (torque to manufacture specs)

you can use better/higher grade bolts, but you still use the original torque specs as published by the manufacture of the part not of the Bolt!
