Thread Plug Gage Set GO NOGO Mixed Lot

Used surplus mixed lot of GO and NOGO thread plug gauges in a segmented plastic organizer case. The lot contains approximately 10 to 12 individual gauge assemblies covering a range of thread sizes and standards. Confirmed visible sizes include 1.3125-12 UNJ and 1-5/16 in.-12 UNJ-2B, with additional assemblies present in various inch sizes. Vermont Gage is confirmed visible on at least one assembly. Other manufacturers are present but not fully legible in photos. UNJ thread forms are aerospace-standard unified inch threads with controlled root radius for enhanced fatigue resistance, commonly specified in aircraft and high-integrity mechanical assemblies. Each assembly consists of a GO member and a NOGO member used to verify internal thread pitch diameter conformance to class-of-fit tolerances. GO and NOGO members are color-coded in accordance with standard gage handling practices. Gauge bodies show typical used surplus wear including surface marks and handling evidence consistent with service in a production or inspection environment. The plastic storage case has multiple compartments accommodating the full set. No calibration certificates are included or implied. Buyers requiring current calibration should arrange recertification prior to use in a controlled inspection environment. All sizes and markings are as observed in photos; buyers are encouraged to confirm individual gauge sizes against their own requirements before purchase.
