It’s definitely an acne thread.

FWIW: @90cummins if you can knurl it, ACME 3/4-10 round internally threaded is available from the usual folks.
McMaster, Roton, etc. Bronze and steel.

All the best,

Peter

I’m aware that I can work around it, just didn’t think it would be a big deal!
Parts for this old iron is pricey😬
Thank you for the advice 👍

3/4-10 isnt a common acme thread.

If you can indeed get the direct replacement for $35.....probably well spent.

If that is your photo in the OP, then it sure doesn't look like Acme. 3/4-10 is the stand UNC coarse thread in that size. I'd at least try a cheap stock nut from the farm store first to verify...

I found a 3/4-10 bolt & nut in my catch all pile and put it up to the acme the thread and it is a perfect match at 10 threads per inch and NO the nut does not turn on the acme rod.
