This is the No Go member of the go\/no go gage pair, designed to reject parts whose pitch diameter exceeds the high limit of tolerance for a Class 6G external thread. Manufactured from Oil Hardened Non-Shrinking Steel (OHNS), it provides stable dimensional characteristics under shop-floor temperature variation. NPL Traceability Certification is included, supporting quality-system documentation requirements. Machinists, quality technicians, and inspection personnel use this gage as part of in-process or final inspection routines.\u003c\/p\u003e\u003cp\u003eThis gage is suited for inspection of small-diameter metric fasteners, threaded inserts, and precision components with M3 x 0.50 external threads conforming to Class 6G tolerance standards. Class 6G is the most common tolerance class for general-purpose metric external threads, making this gage a standard tool in production inspection, incoming material inspection, and toolroom verification environments. It is sold as a single ring gage.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo Go member verifies that pitch diameter does not exceed the upper tolerance limit for Class 6G external threads\u003c\/li\u003e\n\u003cli\u003eM3 x 0.50 thread size covers standard small-diameter metric fasteners and components\u003c\/li\u003e\n\u003cli\u003eOil Hardened Non-Shrinking Steel (OHNS) construction for dimensional stability and wear resistance\u003c\/li\u003e\n\u003cli\u003eNPL Traceability Certification included for quality management system compliance\u003c\/li\u003e\n\u003cli\u003eSingle-ring design for straightforward handling during inspection operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for inspection of M3 x 0.50 metric external threads classified to Class 6G tolerance.

Before use, clean the gage and workpiece threads thoroughly to remove chips, coolant, and debris that could affect readings. Apply a light film of inspection oil to reduce wear on the gage. Store the gage in its protective case when not in use to prevent damage and maintain calibration integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3 x 0.50\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)\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: 34-466-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697088102706,"sku":"34-466-3","price":278.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/128bc0f1ec22690e085e177714af2242.jpg?v=1788349246","url":"https:\/\/voomisupply.com\/products\/spi-34-466-3-threaded-ring-gage-m3x0-5-metric-class-6g-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
