The gage measures a nominal diameter of 0.272 inches and is manufactured from steel for durability in production and inspection environments. Class ZZ Plus gages meet standard go\/no-go inspection requirements for medium-precision hole gauging. Machinists, tool and die makers, and quality control technicians use this gage to confirm dimensional compliance during in-process checks or final inspection.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for shop floor and inspection room use where hole diameter verification is required on drilled, reamed, or bored features. It is a single-piece fixed-limit gage intended for hand use without special fixtures. It is commonly used in metalworking, manufacturing, and precision machining applications where repeatable measurement of small-diameter holes is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.272 inches for precise hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for medium-precision go\/no-go gauging\u003c\/li\u003e\n  \u003cli\u003eSteel construction for resistance to wear in production use\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece fixed-limit design for fast hand gauging\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 1 for individual replacement or stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard fixed-limit plug gage for verifying 0.272-inch diameter holes in metalworking and precision machining applications where Class ZZ Plus tolerance specifications apply.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled by qualified metrology or machining personnel familiar with fixed-limit gauging practice. Clean the gage and the hole being checked before use to prevent debris from affecting the measurement. Do not force the gage into the workpiece, as this can cause false readings or damage the gage. Store the gage in a protective case away from impact and moisture to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.272 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 29-272-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691604803890,"sku":"29-272-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00677a4289d84fa618699b9414ba023b.jpg?v=1788287678","url":"https:\/\/voomisupply.com\/products\/spi-29-272-2-class-zz-plus-plug-gage-0-272-in","provider":"Voomi Supply","version":"1.0","type":"link"}
