Were 12/32 threads fairly common once upon a time. I have an old Model T buzz coil I'm trying to replace the rusty nuts with brass. One post is

They were pretty widely used in the first half of the 20th century.
Make you own 12-32 nuts. Buy a 12-32 tap from Brownells (less than $2), buy some 10-32 nuts, and retap them. For brass nuts you don't even have to worry about drilling them out first.
Sounds like the old 3/16" stove bolt to me.
For all practical purposes a #10 is a 3/16, not a #12. Only
0.002 difference in major diameter between a #10 and a 3/16. A #12 is 0.028 bigger than a 3/16.Dick
Nope, that's a 10-24.

Thanks guys:
I was able to purchase a 12x32 tap from a local gunsmith this morning. Ran it thru the 10/32 brass nuts. Now everything looks pretty.

Actually the stove bolts were 12-24 most of the time. And you can get the tap for that from Brownells also.
And then there is the number 14 machine screw series...
