Do I have to make my own? No joy at fastenall or mcmaster.

Yep. On my 8N tractor there are two nut keepers with square fine
thread 7/16 nuts to bolt body to frame by the lower raditor.

So, either drill/tap a plate, then hacksaw to size and file to square,
or braze a square washer to a hex nut. Either is faster than ordering
a part from anyone's stock.

Just run a tap through a coarse thread square nut.

And you have a "ready stripped" nut just waiting to fail.

It sounds like it'd be simpler to just make one from scratch, but what
I wonder is, why does it need to be square? What would be wrong with a
fender washer and a hex nut?
