Hi. I'm new to this forumn.
We sometimes encounter the minor diameter of form tapped threads falling just over the the upper limit of the thread spec. This causes the thread quality to be a "judgement" call. Some operators claim there are specs specifically for form tapping, but I have yet to find anything like that & they have yet to produce them. Does anyone no of any such standards or specs? I'd like to eliminate the "judgement" part of the quality question from the equation for good.
Thanks.
Dave
