Hello Folks! I am trying to do a study on threaded holes. Our engineering groups are consistently placing MMC on all features of size, especially threaded holes.

I would like to know:
How are you checking threaded features?
Do you provide bonus tolerance?
What is your repeatability/accuracy?

Thanks!
