With Max's NutsAndBolts.v.0.96.2015.06.22 and V4 beta Jan-22-2020 on MacOS 10.13.6, I note an odd bug: while the script appears to work properly for many sizes, both 3/8-16 UNC and 1-8 UNC bolts fail to create the bolt portion. It appears that there is a math related bug somewhere because slightly different pitch values do produce a bolt, although likely with an incorrect thread-form. For example, Max's script supplies 1.588mm as the pitch for a 3/8-16 UNC, the "correct" value is 1.5875 (1 / TPI * 25.4), neither value produces a bolt but 1.5885 does.

For some reason I'm not able to get MoI V3 to run (I always use the V4 betas), so I cannot check to see if this is a V4 bug or something else. I have not dug into the script deeply enough to see why it is failing.
