Title about says it. I need a 7/16 x 20 square nut.

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

In my opinion, yes, you'll have to "roll your own". 7/16-20 is a(n) SAE
thread, so it's highly unlikely to be found as a square nut. I would
expect you'd find only USS threads in square nuts, if any at all.
