It includes both a Go ring and a No Go ring in a single tool, allowing a technician to confirm that a threaded part falls within the acceptable tolerance band for Class 2A fits without switching instruments. Constructed from tool steel, the gage is built for repeated use in production and inspection environments. NIST traceability certification is included, supporting quality systems that require documented measurement standards.\u003c\/p\u003e\u003cp\u003eThis gage is used in machine shops, manufacturing facilities, and maintenance shops wherever 9\/16-24 UNF externally threaded parts must be inspected for conformance. It is appropriate for production-line inspection, incoming quality control, and field verification of machined components. The Class 2A classification covers the standard tolerance range used for most general-purpose threaded fasteners and fittings. Machinists, quality control technicians, and tool-room inspectors are the primary users of this instrument.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo and No Go rings combined in a double-ring design for single-tool thread verification\u003c\/li\u003e\n\u003cli\u003eThread size: 9\/16-24 UNF, Class 2A tolerance classification\u003c\/li\u003e\n\u003cli\u003eTool steel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n\u003cli\u003eNIST traceability certification included for quality management system compliance\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 2.19 inches wide and 0.58 inches in length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of externally threaded components cut to 9\/16-24 UNF Class 2A specifications.

Handle the gage carefully to avoid dropping, which can alter calibration. Store in a protective case away from chips and coolant when not in use. Recalibration against NIST-traceable standards should be performed periodically per your facility quality plan.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Class 2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: Double (Go and No Go)\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\u003eTraceability Certification\u003c\/strong\u003e: NIST included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.19 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.58 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.236 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 23-185-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692014797106,"sku":"23-185-2","price":436.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce01b2a39989767cea7d506a891f3905.jpg?v=1788292035","url":"https:\/\/voomisupply.com\/products\/spi-23-185-2-threaded-ring-gage-9-16-24-class-2a-go-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
