Hello,

I ran across this website and products yesterday

https://www.trueprecisioncorp.com/

Is anyone actually using something like this to measure pitch diameter of threads? It looks like they have been around for a while but im suspicious that no one bothers to do that work.

I've heard the debate of measuring threaded holes with a single straight gage pin and ignoring mmc. the size of holes im talking about are 2-56 thru 3/8-16

Hoping you folks that actually work in metrology can weigh in on how you are actually measuring true position of threaded holes RFS or at MMC. I still think calling them out at MMC is silly but maybe its compelling if folks are actually calculating bonus.
