Sized for a 1\/4-28 thread form, this single-ring gage is used to verify that a male-threaded part meets the minimum material condition required by Class 3A tolerance. A part that passes the Go gage confirms the thread pitch diameter and form are within the upper limit of the tolerance band. Manufactured to NIST-traceable standards, this gage is a standard piece of thread inspection tooling in machine shops, fabrication facilities, and quality-control environments.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for production inspection and incoming quality checks on fasteners, fittings, and machined components carrying a 1\/4-28 UNF external thread. Class 3A represents a tight-tolerance fit class commonly specified in aerospace, hydraulic, and precision mechanical assemblies where thread fit and strength are critical. The single-ring design is the standard form for Go-ring gage applications in bench and floor inspection use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo-class ring gage for 1\/4-28 UNF external thread inspection\u003c\/li\u003e\n  \u003cli\u003eClass 3A tolerance classification for tight-fit precision thread verification\u003c\/li\u003e\n  \u003cli\u003eSingle-ring construction for dedicated Go-function use\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eManufactured to NIST-traceable standards for reliable measurement traceability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of external 1\/4-28 UNF Class 3A threads on male-threaded fasteners, fittings, and machined components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThreaded ring gages are handled and applied by quality control technicians and machinists, not field trades. Store gages in a clean, dry location and handle them without dropping to preserve calibration. Do not force the gage onto a thread; if the Go gage does not pass freely under hand pressure, the part is out of tolerance. Periodic recalibration against NIST-traceable masters is recommended to maintain measurement integrity.\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\u003eGo\/No Go Function\u003c\/strong\u003e: Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Classification\u003c\/strong\u003e: Class 3A\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: 361127020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51728863691058,"sku":"361127020","price":154.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851_f7c49bcc-6f27-4920-b355-d39c6c29c5a6.jpg?v=1788697072","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361127020-threaded-ring-gage-1-4-28-unf-3a-go","provider":"Voomi Supply","version":"1.0","type":"link"}
