Built to Tolerance Class X, this gauge provides the precision required for thread inspection in manufacturing, maintenance, and quality control environments. The Go member confirms that a threaded hole will accept a mating fastener within specification, while the No-Go member confirms the hole has not been overtapped. The chrome-plated gauge members are hardened to RC 70\/72 for long service life and wear resistance. A Certificate of Accuracy is included, and the gauge is calibrated to ISO 17025 accredited standards. Installed and used by machinists, QC inspectors, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis plug gauge is suited for inspection of right-hand 9\/16 inch-12 UNC internal threads in both shop-floor and tool-room settings. The Taperlock 3B handle assembly uses a light blue handle for quick Class 3B identification in a gauge crib or toolbox. The assembly design allows Go and No-Go members to be mounted on the included Taperlock handle for efficient single-tool inspection. Typical applications include production thread verification, incoming inspection, and in-process quality checks on threaded components machined to UNC standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo member pitch diameter of 0.5084 inches and No-Go member pitch diameter of 0.5135 inches for Class 3B thread verification\u003c\/li\u003e\n  \u003cli\u003eTolerance Class X for high-precision thread gauging\u003c\/li\u003e\n  \u003cli\u003eChrome-plated gauge members hardened to RC 70\/72 for extended wear life\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, UNC thread form\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy calibrated to ISO 17025 accredited standards\u003c\/li\u003e\n  \u003cli\u003eLight blue Taperlock 3B handle assembly for fast class identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to inspect right-hand 9\/16 inch-12 UNC internal threads to Thread Class 3B.

Handle the gauge members carefully to avoid nicks or burrs that would affect accuracy. Store gauge members in a protective case when not in use and re-calibrate periodically per your facility quality plan. Do not force the Go member into a thread; if it does not pass freely, the thread is out of specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16 inch-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Class\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Type\u003c\/strong\u003e: Go\/No-Go (Plus\/Minus)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter - Go Member\u003c\/strong\u003e: 0.5084 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter - No-Go Member\u003c\/strong\u003e: 0.5135 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Length - Go Member\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Length - No-Go Member\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Finish\u003c\/strong\u003e: Chrome Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: RC 70\/72\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Design\u003c\/strong\u003e: Assembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Handle\u003c\/strong\u003e: Taperlock 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Color\u003c\/strong\u003e: Light Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Certification\u003c\/strong\u003e: Certificate of Accuracy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibration Standard\u003c\/strong\u003e: ISO 17025 Accredited and Non-Accredited Calibration Certified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimension Type\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VERMONT GAGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 301000000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":68071812333874,"sku":"301143550","price":212.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ffb62edefbf7e2b19900c200be9ed70_bc6b7f1e-6dae-4a3f-8fa7-883fd5f36ae6.jpg?v=1793100150","url":"https:\/\/voomisupply.com\/products\/vermont-gage-301000000-plug-gauge-9-16-12-unc-go-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
