You're right, of course. I suppose the worst case would be removing
square head set screws. As for square nuts, I see them used mostly with
screws, so the torque wouldn't be as much. I don't foresee myself
putting square nuts on anything.

You could always make the wrench out of tool steel, then harden it.

Yeah, I have some O1 & most of the work is in the forging, the heat
treating would be easy enough.

Thanks,
