I had NO idea, so thanks.

We have two Japanese cars, and Japanese is all I've ever owned (with the 
exception of one Dodge Coronet).

Any Metric fasteners I've ever bought have come from all sorts of places, 
from the auto dealer to auto parts jobbers to the corner hardware store. 
I've never encountered any sort of problems with the fit of any bolt in
any 
hole. Nor have I ever been asked which standard of Metric fastener I 
require.

I have a Metric tap and die set. The labeling does not specify the
standard 
to which the tools conform.

I'm thinking either most fasteners must be made to a single standard 
(DIN?), or the standards are so similar you'd need to find yourself in 
unusual situations to see any difference.
