Lee hand priming tool thread size

[garandsrus]

Hi,

What is the thread size for the old style screw in lee priming shell holders? Pictures look like it is about 1/2x20.

Thanks!

I don't know the exact size but can tell you that 1/2X20 is way too coarse.

Do I need to measure one?

Apparently somebody will need to. I don’t know where I hid my thread gauges or I’d measure one of mine. I agree with stubshaft that the threads are way finer than 20 tip... I’m guessing more like 28 or 32.

One of my 50 year old ones measures 5/8x32.
