Class ZZ is the standard tolerance grade for general-purpose GO\/NO-GO inspection work in production environments. This gage is machined from steel and holds a tolerance of 0.0002 inches, making it suitable for verifying hole acceptance in moderate-precision manufacturing and quality control applications. Machinists, toolroom technicians, and QC inspectors are the primary users of this type of instrument.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in shop-floor and inspection-room settings where hole diameter verification is part of a standard quality process. Typical applications include checking drilled or reamed holes in metal fabrication, general machining, and light manufacturing. The 0.467-inch nominal size covers a common bore dimension encountered in mechanical assembly and tooling work. It is well-suited for incoming inspection, in-process checks, and final part verification where Class ZZ tolerances meet the required accuracy level.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade for general-purpose hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.467-inch nominal measurement diameter\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for consistent, repeatable dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production environments\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling during inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose plug gage for use in standard GO\/NO-GO inspection setups where a 0.467-inch nominal bore diameter and Class ZZ tolerance are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled and stored carefully to prevent wear or damage to the precision ground surface. Before use, clean both the gage and the workpiece bore to remove chips, coolant, and debris that could affect measurement accuracy. Never force a plug gage into a hole; light, consistent hand pressure is sufficient for proper GO\/NO-GO determination. Periodic recalibration against certified masters is recommended to maintain traceability and inspection integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.467 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (mm)\u003c\/strong\u003e: 0.0002 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\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: 29-467-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722424615218,"sku":"29-467-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77fdaca237efbfc72d1b9191f9ce3c9f.jpg?v=1788590934","url":"https:\/\/voomisupply.com\/products\/spi-29-467-8-class-zz-plus-plug-gage-0-467-in","provider":"Voomi Supply","version":"1.0","type":"link"}
