276348 Kirk Eppler 2022‑09‑20 Re: Obsolete thread sizes
I occasionally run into 12-24, and some small sizes like 5-40 4-36 on
dividers and calipers, the choices are endless on old stuff.  I just buy
every old tap and die set I find.

I got my pair of 12-20  at $40, but now more availability

You can get your die here

And choices on taps
