Industrial P,PMC.6875-32 UN-2A GO PD.6653 NOT GO PD.6620,SB Go-No-Go Gauge

Industrial P,PMC.6875-32 UN-2A Go-No-Go Gauge, SB Go-No-Go Gauge, is a combined thread and plug gauge used to verify UN-2A threaded parts and related plug diameters. It specifies a GO pitch diameter of 0.6653 and a NOT GO pitch diameter of 0.6620, establishing the acceptable PD window for this thread. This gauge supports fast, on-the-spot inspection of both external threads and internal plug sizes to confirm parts meet the intended tolerances before assembly. Ideal for quality control in machining and manufacturing environments that require precise UN-2A thread verification on industrial components.
