One end carries the Go member and the opposite end carries the No Go member, allowing a technician to confirm both the minimum and maximum material condition of a threaded hole in a single tool. The gage ships with a size 2 handle already installed. A NIST-traceable traceability certification is included, supporting quality-system documentation requirements in manufacturing, aerospace, automotive, and precision machining environments.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspection stations, machine-shop floor use, and incoming-quality-control applications wherever 7\/16-28 UNF threaded components must be verified. The 2B classification covers the standard tolerance range for most commercial and industrial fastener applications. Machinists, quality inspectors, and toolroom technicians are the primary users. The double-end configuration keeps both Go and No Go members on one handle, reducing the number of individual tools needed at a gauging station.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design combines Go and No Go members on a single size 2 handle\u003c\/li\u003e\n  \u003cli\u003eCovers 7\/16-28 UNF thread at 2B tolerance class\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop-floor conditions\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable certification included for quality-system compliance\u003c\/li\u003e\n  \u003cli\u003eHandle included — ready to use out of the package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of 7\/16-28 UNF internal threaded features held to 2B tolerance class.

Store the gage in its case when not in use and keep it clean and lightly oiled to prevent corrosion on the steel members. Never force the Go end through a thread; hand pressure only is required. Recertify the gage on a schedule consistent with your quality management system requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Go \/ No Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\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: 34-397-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710235443506,"sku":"34-397-0","price":336.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9617c0d2b66810ca387e73b19e035360.jpg?v=1788464640","url":"https:\/\/voomisupply.com\/products\/spi-34-397-0-plug-thread-gage-7-16-28-2b-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
