What is the thread size/pitch on the Lee perfect powder measure?

[Max Heat]

I was wondering if it is the same as the autodisk, which I have determined to be 5/8x18. So there is no confusion, the threads that I am referring to are the ones at the bottom of the powder measure, where it screws down into the top of the powder charging die.

The threads on the Lee Perfect Powder Measure are 5/8" x 11TPI UNC. I know I'm 9 years late, but hopefully it will help someone on google in the future as this question has not been posted anywhere else.
