Classified to UNC 3A tolerance, this gage checks the 1-1\/4-7 thread form to confirm that mating parts will not accept an out-of-tolerance fastener or fitting. Every gage ships with a certificate of accuracy and is permanently marked with nominal size, threads per inch, class of fit, and pitch diameters. Licensed metrology technicians and quality control inspectors rely on these gages for production and incoming inspection work.\u003c\/p\u003e\u003cp\u003eThis thread ring gage is suited for inspecting 1-1\/4-7 UNC 3A external threads commonly found in industrial fasteners, pipe fittings, and precision mechanical assemblies. The NoGo ring verifies the minimum material condition of the pitch diameter. When used alongside a matching Go ring gage, it provides a complete functional check of external thread quality in both shop and lab environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNoGo (Minus) classification checks minimum pitch diameter boundary on external threads\u003c\/li\u003e\n\u003cli\u003eConforms to 1-1\/4-7 UNC 3A thread class specifications\u003c\/li\u003e\n\u003cli\u003eSupplied with a certificate of accuracy for traceability and documentation\u003c\/li\u003e\n\u003cli\u003ePermanently marked with nominal size, TPI, class of fit, and pitch diameters\u003c\/li\u003e\n\u003cli\u003eAccepts one line of custom marking up to 25 characters at no additional cost\u003c\/li\u003e\n\u003cli\u003eGo pitch diameter of 1.1572 inches for reference during gage selection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for functional inspection of 1-1\/4-7 UNC 3A externally threaded components.

Keep gages clean and lightly oiled when not in use to prevent corrosion and maintain calibration integrity. Do not force the ring onto a threaded part; the NoGo ring should not pass, and forcing it can damage both the gage and the workpiece. Periodic recalibration per ASME B1.2 or applicable shop standards is recommended to maintain measurement accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: NoGo (Minus) Thread Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGo Pitch Diameter\u003c\/strong\u003e: 1.1572 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGo Length\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 361000000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":68088962187570,"sku":"361175040","price":505.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0157417b2f278395ba4b53927f673bd3_f63fed6e-2449-406d-b25d-2356b9e0bfbb.jpg?v=1793203794","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361000000-thread-ring-gage-1-1-4-7-unc-3a","provider":"Voomi Supply","version":"1.0","type":"link"}
