Built from steel, this go\/no-go style gage checks whether a drilled, reamed, or bored hole falls within tolerance. The nominal measurement diameter is 0.307 inches with a tolerance of 0.0002 inches, meeting Class ZZ Plus accuracy standards. Machinists, tool and die makers, and quality technicians use plug gages like this one to verify hole size quickly and reliably without the need for electronic instrumentation.\u003c\/p\u003e\n\u003cp\u003eThe 29-307-6 is suited for production floor inspection, incoming material verification, and setup validation on CNC or manual machining operations. It is appropriate for both light manufacturing and precision shops where hole tolerances are held to close limits. The compact size and straightforward application make it a standard tool in any inspection kit handling parts in the 0.307-inch bore range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.307 inches for consistent bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable pass\/fail inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under shop conditions\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity for individual tool procurement or kit replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inspection tool for use in any application requiring Class ZZ Plus plug gage verification at a 0.307-inch nominal bore diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, quality technicians, and inspection personnel. Before use, clean both the gage and the bore being checked to remove chips, coolant, and debris that could affect readings or damage the gage surface. Store the gage in its case when not in use to prevent nicks and corrosion. Periodic calibration against a certified master reference is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.307 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  \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: 29-307-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697211801906,"sku":"29-307-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfcd07749b3cefcbdcf408a48ca80b98.jpg?v=1788350589","url":"https:\/\/voomisupply.com\/products\/spi-29-307-6-class-zz-plus-plug-gage-0-307-in","provider":"Voomi Supply","version":"1.0","type":"link"}
