Machined from Oil Hardened Non-Shrinking Steel (OHNS) and supplied as a single-ring unit, it checks M12 x 1.25 pitch threads for conformance to specification during incoming inspection, in-process quality checks, or final verification. NPL Traceability Certification is included, supporting quality management systems that require documented measurement traceability. This gage is used by machinists, quality technicians, and metrology professionals working to metric fastener and thread standards.\u003c\/p\u003e\u003cp\u003eThis gage is suited for production and inspection environments where M12 x 1.25 external threads must be verified against Class 6G fit requirements. Class 6G is the standard tolerance class for general-purpose metric external threads, making this gage applicable across a broad range of machined components, fasteners, and threaded assemblies in both light manufacturing and precision machining settings. The included NPL traceability certification supports ISO-compliant and AS9100 quality programs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo-type ring gage confirms M12 x 1.25 external threads meet minimum material condition for Class 6G fit\u003c\/li\u003e\n\u003cli\u003eOil Hardened Non-Shrinking Steel (OHNS) construction provides wear resistance and dimensional stability\u003c\/li\u003e\n\u003cli\u003eNPL Traceability Certification included for documentation in quality management systems\u003c\/li\u003e\n\u003cli\u003eSingle-ring design for straightforward Go-only verification workflow\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 41111619 for procurement and catalog classification compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for verification of M12 x 1.25 pitch external metric threads manufactured to Class 6G tolerance per standard metric thread specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreaded ring gages are used by quality technicians and machinists and require no installation in the traditional sense. Before use, ensure the gage and workpiece threads are clean and free of chips, burrs, and cutting fluid residue. Apply a light film of gage oil prior to use to reduce wear and protect the gage surface. Store the gage in its case away from temperature extremes to preserve calibration integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Class 6G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: 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)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceability Standard\u003c\/strong\u003e: NPL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 34-487-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695268593970,"sku":"34-487-9","price":271.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7390a689ee0afcfeccd5a7b92a8f702f.jpg?v=1788333379","url":"https:\/\/voomisupply.com\/products\/spi-34-487-9-threaded-ring-gage-m12x1-25-metric-6g-go","provider":"Voomi Supply","version":"1.0","type":"link"}
