Designed for M27 x 2.00 metric threads to Class 6G tolerance, this single-ring gage is machined from Oil Hardened Non-Shrinking Steel (OHNS) tool steel, which provides dimensional stability and resistance to wear over repeated use. A National Physical Laboratory (NPL) traceability certification is included, making this gage suitable for use in quality systems that require documented measurement traceability. Machinists, quality control technicians, and precision manufacturing shops rely on this type of gage as part of a go\/no-go inspection process for threaded components.\u003c\/p\u003e\u003cp\u003eThis gage is used in production and inspection environments where metric threaded fasteners, fittings, or machined parts must be verified against Class 6G external thread tolerances. The No Go gage checks the maximum material limit — a properly machined thread should not allow the No Go ring to pass. It is commonly paired with a Go ring gage of the same thread size and classification to complete the full attribute inspection. Applicable in aerospace, automotive, industrial manufacturing, and general machining operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo Go ring gage confirms external threads do not exceed maximum material condition for Class 6G tolerance\u003c\/li\u003e\n\u003cli\u003eM27 x 2.00 metric thread specification for use with standard coarse-pitch metric fasteners and components\u003c\/li\u003e\n\u003cli\u003eMachined from Oil Hardened Non-Shrinking Steel (OHNS) tool steel for dimensional stability and long service life\u003c\/li\u003e\n\u003cli\u003eSingle-ring design for dedicated No Go inspection use\u003c\/li\u003e\n\u003cli\u003eNPL traceability certification included for quality system documentation and audit compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for attribute inspection of M27 x 2.00 metric external threads manufactured to Class 6G tolerance per applicable metric thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreaded ring gages are handled and used by quality control technicians and precision machinists — no installation in a system is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain dimensional accuracy. Do not force the ring gage onto a thread; if resistance is felt during No Go inspection, the thread is within tolerance and the test is complete. Store in a protective case away from impact, temperature extremes, and abrasive contamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M27 x 2.00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Classification\u003c\/strong\u003e: Class 6G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGo\/No Go\u003c\/strong\u003e: No Go\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Configuration\u003c\/strong\u003e: Single Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Oil Hardened Non-Shrinking Steel (OHNS) Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Standard\u003c\/strong\u003e: NPL Traceability Certification Included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 34-514-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698044272946,"sku":"34-514-0","price":627.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4a339c67be5a4867d6187fd8e6e29ca.jpg?v=1788357090","url":"https:\/\/voomisupply.com\/products\/spi-34-514-0-threaded-ring-gage-m27-x-2-00-class-6g-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
