By joining you are opting in to receive e-mail. It has a diameter of 0.112in (0.28cm). The value listed with the symbol is the ratio of the diameter change to length change. Where an exception to this practice is necessary, the specific feature of the screw thread (such as MAJOR DIA or MINOR DIA) shall be stated beneath the feature control frame, or beneath or adjacent to the datum feature symbol, as applicable. To paraphrase the standard, the geometric tolerances and/or datum references apply to the pitch cylinder diameter unless otherwise specified. Profile Services www.profileservices.ca like this: &METRIC_SIZE &THREAD_SERIES-&THREAD_CLASS x&THREAD_DEPTH[.2] &G6 The catch is that you lose the edit value option on the call-out.
