I've been told that SS doesn't have as high a tensile strength as regular
steel (zinc plated or otherwise). Checking
http://www.ultimategarage.com/metric.html
that's what he says. He mentions getting propery class 70 or better for
automotive use, but doesn't say what the corresponds to in terms of
grading (8.8, 10.9, 12.9). I'd consider SS, but I don't know how to
specify them.

Now, for self-locking, aren't there different types? Ie. prevailing torque
vs. free spinning (stolen from a web page). And also, there are
non-metallic insert and full-metal locking nuts. Did Audi use different
kinds in different places?
