This is the Go member of the Go\/No-Go gage pair, confirming that a threaded workpiece falls within the minimum material condition of the specified tolerance class. The gage is manufactured from Oil Hardened Non-Shrinking Steel (OHNS) tool steel for dimensional stability and long service life. A National Physical Laboratory (NPL) traceability certification is included, supporting quality system documentation requirements. Metrology technicians, machinist inspectors, and quality control personnel use this gage in production and receiving inspection workflows.\u003c\/p\u003e\u003cp\u003eThis gage is suited for inspecting M2.2 x 0.45 externally threaded parts including small screws, pins, and precision fasteners produced to metric Class 6G tolerances. It is applicable in precision manufacturing, aerospace subcontracting, medical device machining, and any production environment requiring documented thread verification at this thread size. The single-ring design accommodates standard handheld inspection use at the bench or on the production floor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGo member for M2.2 x 0.45 metric thread verification at Class 6G tolerance\u003c\/li\u003e\n\u003cli\u003eSingle-ring design for handheld bench or floor inspection use\u003c\/li\u003e\n\u003cli\u003eOil Hardened Non-Shrinking Steel (OHNS) construction for dimensional stability under repeated use\u003c\/li\u003e\n\u003cli\u003eNPL traceability certification included for quality system and audit compliance\u003c\/li\u003e\n\u003cli\u003eVerifies external thread minimum material condition per Class 6G specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of externally threaded components with M2.2 x 0.45 thread form manufactured to Class 6G tolerance per applicable metric thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread ring gages require no installation but should be handled and stored according to standard metrology practices to preserve calibration integrity. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the precision-ground bore. Do not force the gage onto a non-conforming thread, as this can damage the gage and invalidate its certification. Periodic recalibration by a certified metrology lab is recommended to maintain traceability documentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2.2 x 0.45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: 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) Tool Steel\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: 34-461-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689649602866,"sku":"34-461-4","price":528.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8eacd718564d39a8b60386c02d2e7fbf.jpg?v=1788262393","url":"https:\/\/voomisupply.com\/products\/spi-34-461-4-threaded-ring-gage-m2-2-x-0-45-class-6g-go","provider":"Voomi Supply","version":"1.0","type":"link"}
