Manufactured from Oil Hardened Non-Shrinking Steel (OHNS), this single-ring gage provides the hardness and dimensional stability required for accurate, repeatable thread inspection in production and quality-control environments. NPL Traceability Certification is included, supporting compliance with inspection documentation requirements. Licensed machinists, quality technicians, and metrology professionals use this gage to reject out-of-tolerance threaded workpieces before assembly.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for inspecting metric external threads in manufacturing, machining, and precision fabrication settings. It is used in conjunction with a corresponding Go ring gage to confirm that threaded fasteners, shafts, and machined components fall within Class 6G tolerance limits. Typical applications include incoming inspection, in-process quality checks, and final acceptance testing on production lines where M27 x 3.00 threaded parts are produced.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go classification for rejecting oversize or out-of-tolerance M27 x 3.00 threads\u003c\/li\u003e\n  \u003cli\u003eClass 6G tolerance — standard fit class for general-purpose metric external threads\u003c\/li\u003e\n  \u003cli\u003eOil Hardened Non-Shrinking Steel (OHNS) construction for dimensional stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSingle-ring design for dedicated No Go inspection\u003c\/li\u003e\n  \u003cli\u003eNPL Traceability Certification included for quality system documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inspection of M27 x 3.00 external threads manufactured to Class 6G tolerance.

Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain accuracy. Do not force the gage onto a threaded workpiece — a properly manufactured No Go gage should not pass over a conforming thread. Periodic recalibration against traceable standards is recommended to confirm gage wear has not affected accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M27 x 3.00\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: 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 Type\u003c\/strong\u003e: Single\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\u003eStandards\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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 34-516-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691587666226,"sku":"34-516-5","price":805.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4fc58dc8d340573675490e99a609f8b.jpg?v=1788287394","url":"https:\/\/voomisupply.com\/products\/spi-34-516-5-threaded-ring-gage-m27-x-3-00-class-6g-no-go","provider":"Voomi Supply","version":"1.0","type":"link"}
