Machined from tool steel, this single-ring gage is designed for 7\/8-14 UNF threads and conforms to NIST standards, making it a reliable go-to for quality control inspection on the shop floor or in the field. It is used by machinists, quality inspectors, and trade professionals who need to confirm thread tolerance compliance on fasteners, fittings, and threaded components before assembly.\u003c\/p\u003e\n\u003cp\u003eThis gage applies to 7\/8-14 UNF (Unified National Fine) external threads classified to Class 2A tolerances, a standard fit used widely in mechanical assemblies, HVAC components, plumbing fittings, and industrial fasteners. The No Go gage confirms that an externally threaded part does not exceed the high limit of pitch diameter. A properly threaded part should not fully enter the No Go ring gage. This tool is sold as a single-ring unit, suited for dedicated No Go inspection tasks in production or field quality checks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go classification for verifying maximum material condition on Class 2A external threads\u003c\/li\u003e\n  \u003cli\u003e7\/8-14 UNF thread specification for fine-pitch threaded part inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-ring design dedicated to one inspection function\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eConforms to NIST standards for traceable, code-compliant inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of externally threaded parts with a 7\/8-14 UNF thread form meeting Class 2A tolerance requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThreaded ring gages are used by quality control inspectors and machinists and do not require installation in the traditional sense. Before use, ensure the gage and the part being inspected are at the same ambient temperature to avoid measurement error due to thermal expansion. Clean threads on both the gage and the workpiece before gauging to prevent false readings or gage wear. Store the gage in a protected case when not in use to preserve dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14\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 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 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: 361158030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51738707329330,"sku":"361158030","price":272.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851_b264c5e2-de3b-49cf-92ff-b6c38bde119b.jpg?v=1788803158","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361158030-threaded-ring-gage-7-8-14-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
