Manufactured from tool steel, this gage is designed to reject out-of-tolerance parts when the ring engages the thread — a No Go gage should not pass over a conforming thread. It is calibrated to NIST standards and classified to ANSI Class 3A, the tightest fit class in the inch unified thread series. Machinists, quality technicians, and tool-room inspectors use this gage as part of a go\/no-go inspection routine on threaded fasteners and tapped components.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for incoming inspection, in-process quality control, and final inspection of externally threaded parts with a 3\/8-24 UNF thread form. UNF (Unified National Fine) threads are common in precision fastening applications across aerospace, automotive, hydraulic fittings, and instrumentation. The Class 3A designation applies to close-tolerance external threads where minimal clearance and high accuracy are required. This is a single-ring gage, meaning it covers one functional condition — No Go — and is typically used alongside a matching Go ring gage to complete the full thread inspection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go ring gage rejects threads exceeding maximum material condition for Class 3A tolerance\u003c\/li\u003e\n  \u003cli\u003eThread size 3\/8-24 UNF for fine-pitch external thread inspection\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCalibrated to NIST standards for traceable measurement accuracy\u003c\/li\u003e\n  \u003cli\u003eSingle-ring design for dedicated No Go inspection use\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 41111619 for procurement and classification systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of external threads conforming to the 3\/8-24 UNF Class 3A thread standard per ANSI\/ASME B1.2 unified inch screw thread specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThreaded ring gages are handled and used by quality control technicians and machinists — not installed in a system. Before use, clean both the gage and the part thread of chips, oil, and debris to prevent false readings. Do not force the No Go gage; if resistance is felt, the part thread is within tolerance and the gage should not pass. Store ring gages in a controlled environment away from temperature extremes and moisture to preserve calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNF (Unified National Fine)\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\u003eCalibration Standard\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: 361134040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51727074296114,"sku":"361134040","price":165.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851.jpg?v=1788672855","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361134040-threaded-ring-gage-3-8-24-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
