Built from steel, it delivers a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work in production and quality-control environments. Machinists, tool-and-die makers, and QC technicians use plug gages like this one to confirm that a finished bore falls within the specified tolerance range before a part moves to the next stage of assembly or shipment.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in machine shops, manufacturing facilities, and precision fabrication environments where hole-size verification is a routine step in process control. The Class ZZ Plus designation indicates a commercial-grade tolerance level appropriate for inspection of general-purpose bores. It is a hand-held, single-size instrument and is typically used as part of a broader set of plug gages covering a range of nominal diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.565 inches for direct bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade at 0.0002 inches for commercial inspection work\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design suited for go\/no-go pass-fail inspection routines\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use at the machine or inspection bench\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use plug gage for any application requiring verification of a 0.565-inch nominal bore diameter to Class ZZ Plus tolerance standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are used by machinists and quality-control inspectors and require no tools for operation. Before use, ensure the gage and the workpiece bore are clean and free of chips, coolant, or debris to prevent false readings and gage wear. Do not force the gage into an undersized bore, as this will damage the gage surface and compromise accuracy. Store the gage in a protective case away from other metal tooling to preserve the lapped surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.565 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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: 29-565-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51717051285810,"sku":"29-565-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3fb522607a50d0fde1ae6813724de3b.jpg?v=1788535074","url":"https:\/\/voomisupply.com\/products\/spi-29-565-9-class-zz-plus-plug-gage-0-565-in","provider":"Voomi Supply","version":"1.0","type":"link"}
