It is configured as a No Go member, used to verify that a tapped hole has not been cut oversize or out of tolerance. When a properly tapped hole rejects this gage, the thread is confirmed within the upper limit of the 6H tolerance band. Machinists, quality inspectors, and precision tool trades use this gage in production and inspection environments where metric thread conformance is required. Handle is not included and must be sourced separately.\u003c\/p\u003e\n\u003cp\u003eThis gage applies to metric threaded components requiring M20x2.5 thread verification in accordance with 6H classification standards. It is suited for use in manufacturing, machining, and assembly inspection applications where internal thread quality must be confirmed before parts advance in production. The single-end configuration keeps the gage compact and straightforward to use in benchtop or floor-level inspection setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go member confirms internal thread is within the upper 6H tolerance limit\u003c\/li\u003e\n  \u003cli\u003eM20x2.5 thread size covers a widely used metric fastener pitch in mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e6H classification meets standard tolerance requirements for general-purpose metric threaded holes\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 quality documentation and audit compliance\u003c\/li\u003e\n  \u003cli\u003eCalibrated to NIST-traceable standards for accuracy confidence in precision inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard plug gage handles accepting the appropriate shank size.

Always ensure the tapped hole is clean and free of chips, coolant, or debris before gauging. Apply the No Go member by hand without forcing rotation. If the gage enters the hole, the thread is out of tolerance and the part should be rejected or reworked. Store the gage in its protective case when not in use to prevent wear to the precision ground threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20x2.5\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\u003eTraceability Certification\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibration Standard\u003c\/strong\u003e: NIST-traceable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.79 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.79 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 pounds\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: 37-164-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691599626546,"sku":"37-164-1","price":100.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61599c767bd5a2b04ad073abd2ccf7f2.jpg?v=1788287599","url":"https:\/\/voomisupply.com\/products\/spi-37-164-1-plug-thread-gage-m20x2-5-6h-single-end-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
