Sized at 0.229 inches in diameter, this go\/no-go style gage checks whether a bored or drilled hole meets minimum dimensional tolerance. The minus designation indicates the gage is manufactured to the low side of the tolerance band, holding a tolerance of 0.0002 inches. Machined from steel for durability and dimensional stability, this gage is a standard tool for quality control departments, tool rooms, and production floor inspection.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for dimensional inspection tasks in manufacturing environments where hole diameter verification is required. It is commonly used by machinists, quality technicians, and tool and die professionals working with tight-tolerance bored holes, drilled passages, and reamed features. Class ZZ gages are appropriate for general-purpose inspection where high-precision master-grade tooling is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.229 inch nominal diameter for direct hole size verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance class suited for general-purpose inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus designation — manufactured to the low side of the tolerance band\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for consistent, repeatable measurements\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ minus plug gage for inspecting 0.229 inch diameter holes in machined workpieces across standard production and tool room environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages should be handled with clean, dry hands or inspection gloves to prevent corrosion from skin oils. Store the gage in its case or on a protective surface away from other tooling to prevent contact damage. Do not force the gage into a hole — if resistance is felt, the hole is undersize or contains debris. Periodic cleaning and calibration checks against a known standard are recommended to maintain accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.229 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 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\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: 19-229-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692467716402,"sku":"19-229-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/893c855254c74d46323af7e02d30f3e5.jpg?v=1788297982","url":"https:\/\/voomisupply.com\/products\/spi-19-229-4-class-zz-minus-plug-pin-gage-0-229-in","provider":"Voomi Supply","version":"1.0","type":"link"}
