Classified as a No Go gage to the Class 3A tolerance standard, it checks that a mating thread does not exceed the maximum material condition limit. The gage is manufactured from tool steel for wear resistance and dimensional stability under repeated use. It conforms to NIST standards, making it suitable for quality-control applications where traceability and accuracy are required. Machinists, tool-room technicians, and quality inspectors use this gage during production inspection and incoming parts verification.\u003c\/p\u003e\n\u003cp\u003eThis gage is designed for inspecting 1\/4-28 UNF external threads to Class 3A tolerance, which represents a close-tolerance fit commonly specified in precision mechanical assemblies, aerospace fastener applications, and instrumentation. A No Go gage is applied after the Go gage check: if the No Go ring assembles onto the threaded workpiece, the part is out of tolerance and must be rejected. This single-ring design is intended for bench inspection or in-line quality checks in machine shops and manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go classification confirms maximum material condition rejection for Class 3A external threads\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF thread size covers a widely used fine-thread fastener specification\u003c\/li\u003e\n  \u003cli\u003eTool steel construction provides durability and resistance to wear over extended inspection use\u003c\/li\u003e\n  \u003cli\u003eSingle-ring design allows direct, unambiguous pass-fail gauging\u003c\/li\u003e\n  \u003cli\u003eConforms to NIST standards for traceability in calibrated inspection environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of 1\/4-28 UNF externally threaded workpieces held to Class 3A tolerance.

Store the gage in its protective case when not in use to prevent damage to the thread form. Calibrate or re-certify the gage periodically per your facility's quality management system requirements. Do not force the gage onto a workpiece thread; applied force can damage the gage and produce false readings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Class 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGo\/No Go\u003c\/strong\u003e: No Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Configuration\u003c\/strong\u003e: Single Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111619\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: 361127040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51733024276786,"sku":"361127040","price":155.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851_01d5d0b7-e4b8-419e-86a8-aa7ce406f0b0.jpg?v=1788750674","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361127040-threaded-ring-gage-1-4-28-unf-3a-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
