This is the Go member of a Class 2A gage set, meaning it confirms that a threaded part falls within the acceptable maximum material condition limit. Machined from tool steel and traceable to NIST standards, it is used by machinists, quality inspectors, and tool-room technicians in production and incoming inspection environments where thread conformance to Unified National Fine specifications must be documented.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspection of small-diameter external threads in precision fastener manufacturing, aerospace sub-assembly, medical device production, and general machining shops. The 3-56 UNF thread designation indicates a number 3 diameter screw with 56 threads per inch, a fine-pitch configuration common in miniature hardware and instrument assemblies. Class 2A tolerance reflects the standard fit classification covering the majority of general-purpose externally threaded fasteners and fittings produced to Unified thread standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGo ring gage confirms external thread pitch diameter is within Class 2A maximum material limits\u003c\/li\u003e\n  \u003cli\u003e3-56 UNF thread form for fine-pitch, small-diameter inspection applications\u003c\/li\u003e\n  \u003cli\u003eMachined from tool steel for wear resistance and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eSingle-ring design for dedicated Go-function gauging\u003c\/li\u003e\n  \u003cli\u003eManufactured and calibrated to NIST-traceable standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of external 3-56 UNF Class 2A threaded components.

Handle with clean, dry hands or lint-free gloves to prevent contamination of the gage bore. Store in a protective case away from abrasive materials and temperature extremes to preserve dimensional accuracy. Periodic re-calibration against NIST-traceable masters is recommended per the inspection interval requirements of your quality management system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-56\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: 2A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGo\/No Go\u003c\/strong\u003e: 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: 361108510\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51748939825458,"sku":"361108510","price":238.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab93e4c0f1b5adc81b3328ccfeeb851_3d796740-afb8-44f0-bc63-09892348aac2.jpg?v=1788900218","url":"https:\/\/voomisupply.com\/products\/vermont-gage-361108510-threaded-ring-gage-3-56-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
