Manufactured from tool steel, this single-ring gage is used to inspect 1\/4-20 UNC thread forms in production and quality-control environments. It conforms to NIST standards, making it suitable for applications where traceable measurement accuracy is required. Licensed machinists, quality inspectors, and precision tooling technicians rely on this type of gage to catch out-of-tolerance parts before they move further down the assembly process.\u003c\/p\u003e\u003cp\u003eThis gage is suited for shop-floor and inspection-room use wherever 1\/4-20 UNC externally threaded components are manufactured or verified. Typical applications include fastener production, machined component inspection, and incoming quality control for threaded hardware. The No Go function confirms that threads have not been cut oversized or under-toleranced, which is critical in assemblies requiring consistent thread engagement and load-bearing reliability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo Go ring gage — confirms threads do not exceed Class 2A maximum material limits\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC thread form — standard unified coarse thread for broad fastener applications\u003c\/li\u003e\n\u003cli\u003eClass 2A classification — the most common tolerance class for general-purpose external threads\u003c\/li\u003e\n\u003cli\u003eSingle-ring design — dedicated No Go function for clear, unambiguous inspection results\u003c\/li\u003e\n\u003cli\u003eTool steel construction — provides durability and dimensional stability under regular shop use\u003c\/li\u003e\n\u003cli\u003eNIST-standard conformance — supports traceable quality inspection processes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of external 1\/4-20 UNC Class 2A threaded components such as fasteners, studs, and machined parts requiring conformance to unified coarse thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreaded ring gages are handled and used by quality inspectors or machinists — no installation in the traditional sense applies. Store the gage in a clean, dry environment and handle it with clean gloves or lint-free cloths to prevent corrosion and dimensional drift from skin oils. Do not force the gage onto a thread; a No Go gage that spins freely onto a thread indicates a nonconforming part. Calibration intervals should follow your facility's quality management system requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Class 2A\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\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\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: 361126030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51738496762162,"sku":"361126030","price":154.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851_82f46b1e-8e52-4ee8-998a-92ee195ffb92.jpg?v=1788800280","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361126030-threaded-ring-gage-1-4-20-unc-2a","provider":"Voomi Supply","version":"1.0","type":"link"}
