Thread size on a Dillion press handle?

[jeff43]

Does anybody know what size the threads are on the ball on top of the handle on a Dillion 550?

Call or email Dillon.

With a dirty finger and a piece of white printer paper, lay the paper across the threads, rub the paper with your dirty finger. I use a digital caliper to measure how many threads that left a mark on the paper( 8 marks in 1/2 inch would be 16 threads per inch). Then measure the size of the shaft.

This is not hard, I have used the "trick or hack" many times over the years.

That is where these come in very handy.

The thread gage from any tap and die set will give you the info you need, too.

I got some of those , but it didn’t go up big enough

Measure the OD of the threads. Count the number of threads and measure the total distance over the threads. Can probably figure it out from that.

Google search shows 5/8-18

I got the largest set, even though I usually don't have anything that big.  Better to have and not need
