Having a nut wind a stud out during repair is trivial compared with
having a nut wind itself off a stud while you're diriving down a
highway.  This seems to be a very selfish preference on your
mechanic's part.

Well, it seems to have worked roughly 5 x 4.1 million times for Audi.
Actually - this is a little secret you can pass on to your mechanic
friend - they're _plated_ to prevent corrosion.  Try suggesting that
he cuts one in half to see just how far in the 'copper content' goes.

> c) he prefers 13mm (more to grip).

Huh?  He gets 35 NM with his FINGERS?  Most of us find 12mm quite
adequate - but then we use WRENCHES.
