It checks whether a bored, drilled, or reamed hole meets a specified diameter tolerance, serving as a go\/no-go reference tool. This gage is sized at 0.325 inches in diameter with a tolerance of 0.0002 inches, making it suitable for close-tolerance work where dimensional accuracy is critical. Constructed from steel, it is built to withstand repeated use in shop-floor conditions. Machinists, quality control inspectors, and tool room technicians are the primary users of this type of instrument.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in production inspection and quality assurance settings where hole diameter verification is required. Class ZZ Plus is a standard designation for working gages used to check workpiece holes rather than for calibrating other gages. It is appropriate for both job shop and production floor applications where steel plug gages at this diameter range are specified by the inspection plan or engineering drawing. The compact size and light weight make it easy to handle during repetitive inspection cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.325-inch nominal diameter for precise hole measurement\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance meets Class ZZ Plus gage accuracy standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated shop-floor use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy one-hand handling\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package ready for immediate use upon receipt\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style working plug gage for use in standard hole inspection applications requiring a 0.325-inch diameter Class ZZ Plus gage.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality inspectors and require no installation in the traditional sense. Before use, clean the gage and the workpiece hole with a lint-free cloth to remove chips, oil, or debris that could affect the reading. Handle the gage carefully to avoid dropping, which can alter dimensional accuracy. Store the gage in its protective case when not in use to prevent corrosion and surface damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.325 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage 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: 29-325-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692253020466,"sku":"29-325-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac482873a4d0ce17a6fe586e9617d1e6.jpg?v=1788295229","url":"https:\/\/voomisupply.com\/products\/spi-29-325-8-class-zz-plus-plug-gage-0-325-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
