Classified as a Go gage to Class 6G tolerance, it confirms that a machined or formed thread falls within the acceptable minimum material condition for proper mating assembly. Manufactured from Oil Hardened Non-Shrinking Steel (OHNS), the gage maintains dimensional stability under shop conditions. It ships with an NPL Traceability Certification, supporting quality control documentation requirements in calibrated inspection environments. Machinists, quality technicians, and tool-room inspectors use this gage as part of thread inspection routines on production and prototype parts.\u003c\/p\u003e\u003cp\u003eThis gage is suited for inspection of M12 x 1.75 externally threaded parts in manufacturing, machining, and assembly environments. It is used wherever metric Class 6G thread tolerance verification is required, including automotive, aerospace, and general industrial applications. The Go gage is used in combination with a No-Go gage to establish a complete pass-fail inspection protocol for external threads. Single-ring construction keeps handling simple and reduces the risk of confusing Go and No-Go results during high-volume inspection workflows.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo gage confirms threads meet Class 6G minimum material condition\u003c\/li\u003e\n\u003cli\u003eM12 x 1.75 metric thread size for standard metric fastener inspection\u003c\/li\u003e\n\u003cli\u003eOil Hardened Non-Shrinking Steel (OHNS) construction for dimensional stability\u003c\/li\u003e\n\u003cli\u003eSingle-ring design for straightforward Go-only inspection tasks\u003c\/li\u003e\n\u003cli\u003eNPL Traceability Certification included for quality system compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of external metric threads sized M12 x 1.75 to Class 6G tolerance per applicable metric thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread ring gages are handled and used by quality technicians and machinists in inspection environments, not installed in mechanical systems. Store the gage in its protective case when not in use to prevent damage to the thread form. Clean threads on both the gage and the workpiece before each use to ensure accurate results. Periodic recalibration against a traceable standard is required to maintain measurement integrity; follow your facility quality program for recalibration intervals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.75\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111619\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: 34-489-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51708988653874,"sku":"34-489-5","price":273.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/871dd8b60321f0868556d836ae3cb184.jpg?v=1788449660","url":"https:\/\/voomisupply.com\/products\/spi-34-489-5-threaded-ring-gage-m12x1-75-class-6g-go","provider":"Voomi Supply","version":"1.0","type":"link"}
