What size is the inside thread on the RCBS Uniflo powder measure. It's greater than 1/2 inch. but the minor dia measures .513???

9/16ths X ??? 5/8ths X 18 tpi ???

I want to make some spout adapters but need to know this first.

Help Anyone?

Thanks in advance.

If you are talking about the threads at the bottom for the drop tube to thread into, it's 9/16x18.

I just checked this on my Uniflow measure.

Yes It is 9/16x18. I took a bolt with this thread and bored it out length-wise with first a 1/4" and then a 3/8" drill, rounded the corners of the hex head until it matched the inside diameter of a Lee powder thru the expanding die and then mounted my RCBS powder measure on it so that the measure sat on/in whatever expand die I was using. If you "cone" the hole that sits up inside of the PM shaft, then the powder drops straight thru then no bridging or hung up grains. LLS

Thank you both, I'll get busy making some that will fit my setups.
