recently our qa inspector used a standard plug gauge to inspect "1.000-12UNJF-3B per MIL-S-8879, with root radius .005/.007". now we have a bunch non-conforming parts. the standard plug gauge does not check root radius on a female thread. the root radius is an additional requirement over MIL-S-8879, the inspector should use reprorubber to get the form of the root and put on optical comparator. do you, your company have/has a chart to tell the floor inspector what inspection instruments should be used for what feature ?
