OK, thanks. The answer is, the friction/force formula is more
complicated than it appears. I meant to question it, eg. to illuminate
it, not to doubt it. Clearly the factory went to the bother -- and
there's not too many left-handed-lug-nut foolishness in mechanical
design.

I SUPPOSE I could go read a book or sumptin' :-)

Thanks for the additional info!
