12x32 threads

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
10/32 and the other 4 are larger than a 10 and smaller than a 1/4. I'm in a
quandry. Any suggestions

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.

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...
