In this Question Line video, Jason answers the submitted question below regarding the use of the MMC modifier on threaded holes:
I’ve heard that it’s not good practice to use the MMC modifier on threaded features, is this true?
In this video, Jason breaks down what the MMC modifier does and how bonus tolerance works, walking through an example of a clearance hole. He then considers applying it to a threaded hole, shown above, discussing how the ASME standards treat thread size, what that means for measurement, and why there is minimal benefit of applying MMC on a threaded hole.
