It measures a nominal diameter of 0.487 inches with a tolerance of 0.0002 inches, providing the precision required for quality control checks in production and toolroom environments. Constructed from steel, this go\/no-go style gage is a reliable tool for machinists and metrology technicians confirming part conformance to print. The compact form factor and light weight make it easy to handle during high-volume inspection work.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in manufacturing facilities, machine shops, toolrooms, and inspection departments where hole diameter verification is part of the production or QC process. It is appropriate for checking drilled, reamed, or bored holes in ferrous and non-ferrous workpieces. The Class ZZ Plus classification indicates a commercial-grade tolerance standard, making this gage a practical choice for production-floor go\/no-go inspection rather than master or reference gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.487 inches for precise hole verification\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches meets Class ZZ Plus classification standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and wear resistance under repeated use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand operation during inspection\u003c\/li\u003e\n  \u003cli\u003eIndividual packaging protects the gage surface and maintains calibration integrity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use plug gage for inspecting machined holes with a nominal diameter of 0.487 inches in standard production and toolroom inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, quality technicians, and metrologists. Before use, clean the gage and the bore being checked to remove chips, coolant, and debris, as contamination will produce false readings. Do not force the gage into a bore; firm hand pressure only is appropriate to avoid damaging the gage surface or the workpiece. Store the gage in its protective case when not in use to prevent surface wear and corrosion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.487 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0051 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 29-487-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690332160306,"sku":"29-487-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4eba779df15a8c9acae0b152ffd0515.jpg?v=1788268939","url":"https:\/\/voomisupply.com\/products\/spi-29-487-6-class-zz-plus-plug-gage-0-487-in","provider":"Voomi Supply","version":"1.0","type":"link"}
