We have been having an issue with a Supplier drilling threaded holes that are over sized(minor diameter). So we requested a Corrective Action. In their 8D report, They stated they will start checking the threaded holes using a Gauge Pin for minor diameter. Gauge Pin size: 5.154. The standard calls out for minor diameter of 4.917 - 5.153 for an M6x1 thread, Now the debate here is, Should the NOGO Gauge Pin be 5.154 or 5.153, I've searched google and seems like everyone is on different sides of the fence on this.
Thanks!
