It measures a nominal diameter of 0.818 inches with a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection workflows where tight dimensional control is required. Constructed from steel for durability and dimensional stability, this gage is a standard tool for machinists, toolmakers, and quality control technicians working to close tolerances on drilled, reamed, or bored features.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in machine shops, manufacturing facilities, and inspection departments to confirm that bored or drilled holes fall within specified dimensional limits. Class ZZ Plus gages are commonly applied in production inspection where periodic checking of hole diameter is needed to maintain process control. The 29-818-2 is appropriate for use on both ferrous and non-ferrous workpieces where a 0.818-inch nominal hole size is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.818 inches for precise hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable go\/no-go verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides dimensional stability and resistance to wear\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suits individual bench or field inspection use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for use in go\/no-go inspection setups requiring a 0.818-inch nominal diameter measurement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, toolmakers, and quality control inspectors. Clean and lightly oil the gage before use to prevent corrosion and ensure accurate contact. Do not force the gage into a hole, as this can damage the gage or alter the workpiece feature. Store in a protective case away from temperature extremes 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: 0.818 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\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: 29-818-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715802202418,"sku":"29-818-2","price":15.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80eada22ea2e1b69e701c8d4569cf093.jpg?v=1788518508","url":"https:\/\/voomisupply.com\/products\/spi-29-818-2-class-zz-plus-plug-gage-0-818-in","provider":"Voomi Supply","version":"1.0","type":"link"}
