One end is the Go member and the other is the No Go member, allowing a single tool to confirm both the minimum and maximum thread condition in one setup. The gage is manufactured from steel for wear resistance and dimensional stability under shop conditions. A handle is included and sized at Handle Size 2. Traceability certification to NIST standards is included, making this gage suitable for quality-controlled environments, inspection departments, and production floor verification.\u003c\/p\u003e\n\u003cp\u003eThis gage is used wherever 7\/16-14 threaded holes must be verified to 2B class tolerance — a common requirement in general manufacturing, machining, fabrication, and maintenance repair operations. Typical applications include incoming inspection of threaded fastener holes, in-process thread verification on CNC or manual machining operations, and final inspection sign-off. The included NIST traceability certificate supports ISO and AS9100-type quality management documentation requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design combines Go and No Go members in a single gage body for efficient thread verification\u003c\/li\u003e\n  \u003cli\u003eCalibrated to 7\/16-14 UNC thread form at 2B class tolerance\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and dimensional stability through repeated use\u003c\/li\u003e\n  \u003cli\u003eHandle Size 2 included — no separate handle purchase required\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification included for quality system documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to inspect internal 7\/16-14 UNC threads held to ASME B1.2 2B class tolerance limits in any material or application where that thread form is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread gages are handled and stored by quality technicians, machinists, or inspection personnel — not installed in a system. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel members. Do not force the Go end through a thread that resists entry, as this can damage both the gage and the workpiece. Store in the protective case or pouch away from other metal tooling to prevent nicking the gage members.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Double End Plug, Go and No Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Size\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Standard\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 34-393-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51707420082482,"sku":"34-393-9","price":161.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04acd4fcd5f1f8d51991432cccaacd28.jpg?v=1788440219","url":"https:\/\/voomisupply.com\/products\/spi-34-393-9-plug-thread-gage-7-16-14-2b-go-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
