Thanks Roger Shoaf, that makes sense. I need to make it 5/16 x 32. Sounds
like that might workout because the diameter of the rod is .311 right now.

The diameter of the rod should be the nominal dimension of the thread. So
if you wanted to cut 1/4 x 20 threads you would start with a 1/4" rod. In
actual practice the diameter of the rod should be a few thousandths of an
inch smaller than the nominal dimension.

What size threads do you need to cut?

If you are not part of the solution, you are not dissolved in the solvent.

I have a small job that requires threads be cut on the OD of a round
rod.
I
have looked all around for a chart that indicates the outside diameter a
rod
should be when using a die to cut threads. Something along the lines of
a
tap drill chart, but for dies? Any takers?
