Manufactured from steel, this gage checks 7\/16-14 thread size to the 6H tolerance class per ANSI standards. It is used by machinists, quality control technicians, and maintenance professionals to confirm that tapped holes reject oversized or out-of-tolerance threads before assembly. The gage ships without a handle; a Size 2 handle is required for use and must be sourced separately. NIST traceability certification is included, supporting documentation requirements in calibrated inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for production floor inspection, incoming quality checks, and maintenance applications where 7\/16-14 internally threaded components must be verified for conformance. It is appropriate for both shop-floor and tool-room environments where ANSI-compliant thread inspection is required. The single-end No Go design allows focused rejection testing without the Go member, making it a practical addition to an existing gage set where the Go member is already on hand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go member checks that internal threads do not exceed maximum material condition\u003c\/li\u003e\n  \u003cli\u003e7\/16-14 thread size with 6H tolerance classification per ANSI standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration for straightforward rejection testing\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification included for calibrated inspection documentation\u003c\/li\u003e\n  \u003cli\u003eAccepts a Size 2 handle (handle not included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with a Size 2 plug gage handle (not included) to inspect 7\/16-14 internally threaded components requiring 6H tolerance class verification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread gages are inspection tools and do not require permanent installation. A licensed or trained metrologist, machinist, or QC technician should perform thread inspection using a properly sized handle. Do not force the No Go gage into a thread; entry of more than two turns indicates the thread is out of tolerance. Store gages in a protective case away from abrasives and corrosive materials to preserve calibration integrity.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: No Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\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 (not included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 34-278-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51712152076594,"sku":"34-278-2","price":79.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aafeadbedb83d359ccceaadb081611dc_07832a0b-bd22-430c-b929-162be59249f5.jpg?v=1788484508","url":"https:\/\/voomisupply.com\/products\/spi-34-278-2-plug-thread-gage-7-16-14-6h-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
