It is used to verify bore and hole dimensions by checking whether a workpiece feature falls within acceptable size limits. Class ZZ designates a commercial-grade tolerance level commonly applied in general inspection and production checking environments. The minus designation means the gage is ground to the lower tolerance boundary, making it appropriate for go\/no-go inspection workflows where the gage must pass through an acceptable hole. Machinists, tool and die technicians, and quality control inspectors are the primary users of this type of gage.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is suited for dimensional inspection of drilled, reamed, or bored holes in manufacturing, repair shop, and production floor environments. It is used across metalworking, mechanical assembly, and fabrication settings wherever a 0.575-inch nominal hole diameter must be verified. The gage is handled by inspection personnel performing in-process or final acceptance checks on machined components. Its compact size makes it practical for bench inspection and in-line quality checks alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance classification for general-purpose commercial inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance ground to the lower boundary for reliable go\/no-go verification\u003c\/li\u003e\n  \u003cli\u003e0.575-inch nominal diameter for direct bore and hole inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability during repeated use\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches ensures consistent measurement accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage for use in any inspection application requiring verification of a 0.575-inch nominal bore or hole diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists, quality inspectors, and tool room technicians. Store the gage in a protective case when not in use to prevent surface damage that could affect dimensional accuracy. Clean the gage and the workpiece bore before use to remove chips, coolant, or debris that could cause false readings. Never force the gage through a hole, as this can damage both the gage and the workpiece surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: Class ZZ Minus\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\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: 19-575-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697150394674,"sku":"19-575-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6de22ae0b3978128ef486148f47d2f6e.jpg?v=1788349937","url":"https:\/\/voomisupply.com\/products\/spi-19-575-0-class-zz-minus-plug-pin-gage-0-575-in","provider":"Voomi Supply","version":"1.0","type":"link"}
