It is used to confirm that a tapped hole has not been cut undersize or otherwise out of tolerance in a way that would cause interference during assembly. The gage measures approximately 1.31 inches in length with a 0.24-inch diameter gage member and weighs 0.044 pounds. A handle is not included and must be sourced separately. Machinists, quality control inspectors, and toolroom technicians use this gage as part of a go\/no-go inspection routine on production or maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspection of M6x1 metric internally threaded features in manufacturing, machining, and mechanical assembly environments. It applies wherever 6H-class thread tolerance verification is required, including precision component production, incoming inspection of fastener bosses, and field verification of tapped holes in equipment repair. The single-end format keeps the gage compact and easy to handle in confined inspection setups. It ships as a single unit per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go member verifies internal M6x1 threads do not exceed maximum material condition under 6H tolerance\u003c\/li\u003e\n  \u003cli\u003e6H classification aligns with standard metric thread tolerance for general-purpose fastening applications\u003c\/li\u003e\n  \u003cli\u003eSingle-end design provides a compact, dedicated No Go inspection tool\u003c\/li\u003e\n  \u003cli\u003eANSI traceability certification included for documentation and quality system requirements\u003c\/li\u003e\n  \u003cli\u003eCalibrated to NIST-traceable standards for reliable inspection accuracy\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.044 pounds with a 0.24-inch gage member diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of M6x1 internally threaded features manufactured to 6H tolerance class per ANSI metric thread standards. Intended for use with a separately purchased handle compatible with single-end plug gage members of this diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread gages are inspection tools, not cutting tools. Install the gage member into a compatible handle before use, following the handle manufacturer's seating instructions. The No Go member should not pass fully through a correctly tapped hole. If the No Go gage passes, the thread is out of tolerance and the part should be rejected or reworked. No power isolation is required for use, but follow your facility's part-handling and FOD (foreign object debris) control procedures during inspection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M6x1\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\u003eHandle Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 0.24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.044 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibration Standard\u003c\/strong\u003e: NIST\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: 37-149-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714262597938,"sku":"37-149-2","price":78.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b415d31356d50c2765996f0723855591.jpg?v=1788498492","url":"https:\/\/voomisupply.com\/products\/spi-37-149-2-plug-thread-gage-m6x1-6h-class-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
