Cheers, Chris The complete thread designation is made up of values for the thread form and the tolerance. (ref) mm in. Using the principles of GO/NOGO gaging for internal threaded parts, a GO thread plug gage checks the minimum major diameter and minimum pitch diameter, and a NOGO thread plug gage checks that the maximum pitch diameter is not exceeded. 3. If not, IF returns "Fail". The Excel workheets from someone else may have used 6 (or 5.15) standard deviations, so when you past those values into your program based on 1 standard deviation, they don’t match.
