The gauge is hardened steel construction and conforms to ISO 1502 standard gauge-making requirements; it is NIST-traceable (NIST vide 21-53922-B) and ships with a Certificate of Inspection dated 13-10-2021 confirming actual pitch diameter of 14.9797 mm (specified 14.9857 ±0.0090 mm) and minor diameter of 14.3382 mm (specified 14.3442 ±0.0090 mm). The GO member verifies that a threaded workpiece can be fully assembled — a part that passes the GO gauge is confirmed to be within the maximum material condition limit for 6g tolerance class, which is the standard medium-fit external thread tolerance used for the vast majority of metric fastener applications. This gauge is suited for use in production inspection and quality control environments where M16x1.5 fine-pitch threads must be verified on bolts, studs, shafts, and other externally threaded components.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct
