The gage set includes both a Go ring and a No Go ring, allowing machinists and quality technicians to confirm that a threaded part falls within the acceptable tolerance range for a Class 2A fit. Manufactured from tool steel, this gage is built for repeated use in production and inspection environments. NIST traceability certification is included, supporting documentation requirements for calibrated inspection tooling.\u003c\/p\u003e\u003cp\u003eThis gage is used in machine shops, production floors, and quality control departments wherever 7\/16-14 UNC externally threaded parts must be inspected against Class 2A thread tolerance standards. Typical applications include incoming inspection of purchased fasteners, in-process verification during CNC or manual machining operations, and final inspection before assembly. The double-ring configuration keeps both the Go and No Go gages together as a matched set for the same thread specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo and No Go rings included in a single double-ring set for complete Class 2A tolerance verification\u003c\/li\u003e\n\u003cli\u003eDesigned for 7\/16-14 UNC external thread inspection\u003c\/li\u003e\n\u003cli\u003eConstructed from tool steel for durability and dimensional stability under repeated use\u003c\/li\u003e\n\u003cli\u003eNIST traceability certification included to support calibrated inspection documentation requirements\u003c\/li\u003e\n\u003cli\u003eCompact form factor suitable for bench, line, or incoming inspection use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of externally threaded parts with a 7\/16-14 UNC thread form manufactured to Class 2A tolerance specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreaded ring gages are used by machinists, quality technicians, and inspection personnel — not installed in a system but handled as calibrated inspection instruments. Keep gages clean and lightly oiled when not in use to prevent corrosion and preserve dimensional accuracy. Do not force the No Go ring onto a part; resistance indicates the thread is at or outside the tolerance boundary as intended. Store in a protective case away from impact, extreme temperatures, and abrasive contaminants to maintain calibration integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Class\u003c\/strong\u003e: 2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Go and No Go\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Configuration\u003c\/strong\u003e: Double Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Standard\u003c\/strong\u003e: NIST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.618 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 23-169-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715040051506,"sku":"23-169-6","price":299.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25eefd92c28e0789d5103bb890e68980.jpg?v=1788509153","url":"https:\/\/voomisupply.com\/products\/spi-23-169-6-threaded-ring-gage-7-16-14-class-2a-go-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
