That's an interesting idea. Might a wrench with slightly open jaws like
that actually be easier to use on square nuts? With square nuts, you
certainly don't need as close a fit as you do with hex nuts to prevent
damage and slipping. With the slightly open jaws, you could just push the
wrench into the nut until it wedged on the nut and get a tight fit (at 3
points). A problem with adjustable wrenches is that when you adjust them
to be snug, they tend not to come off, and or are hard to put on, so you
have to either open them just slightly to use them, or tighten and loosen
them for every turn. Might an open jaw design actually make it easier to
get on and off and still allow a fairly tight fit and not risk much damage
if you only used it on square nuts???

Damn, you're good! That makes perfect sense. And since only the
diagonally opposite points are actually in contact with the nut, it
wouldn't matter if the jaws are parallel or not.

So maybe it was intentionally designed that way if the expected use was for
square nuts?

If we wanted to be generous, we could say so. G

Bob - got any square nuts you can try it on ...

Ah, damn ... I took it back to the dump (Swap Shop) yesterday!

Thanks,
