Help with a Lee Universal expanding die

[guywitha3006]

Did not know where else to put this question/favor, but would someone be able to tell me the size of the threads on the inside of the die (the threads on the top piece that holds the inserts down)? Thanks in advance!

1/8 x 27 NPT

I think it is closer to 1/2 or 5/8 not 1/8?

Oh boy, right you are. 1/8 x 27 NPT is the threads for the decapping pin collet on their sizing dies. Sorry!

That's alright thank you anyways.

I am not a machinist by any stretch, but my calipers say it it 1/2" with 5 threads in about 3/8" so my guess is 1/2 X 15 or 16. ?

[mac60]

The pitch is 16 tpi. It's probably 5/8 x 16.
