Reading ETKA hardware #s

[passat TS]

Careful.

Huw is right, stainless steel does not have the same strength for some of 
the applications (suspension, engine).

It does look good on you valve cover, but not on you stub axles.

I personally use 12.9 on anything that I suspect (brakes is an example) will 
be under stress.

Carlos.

ps. a good source of metric hardware is Maryland Metrics.
