The gage is manufactured from steel and holds a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work in precision machining, fabrication, and quality control environments. Class ZZ gages are designed for general-purpose inspection use. Licensed machinists, QC inspectors, and tool-room technicians are the primary users of this gage.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is applied in shop-floor and inspection environments where bore diameter verification is required. It is well suited for checking drilled, reamed, or punched holes in production parts where dimensional compliance must be confirmed before assembly. The minus designation means the gage is manufactured to the lower end of the tolerance band, providing a consistent and repeatable reference for minimum hole acceptance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance grade for general-purpose dimensional inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation for lower-limit tolerance verification\u003c\/li\u003e\n  \u003cli\u003e0.244-inch nominal diameter for precise bore checking\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for reliable go\/no-go inspection accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard addition to Class ZZ plug gage sets used in general-purpose machining and quality inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by QC inspectors and machinists and require no permanent installation. Always clean the gage and the bore being checked before use to prevent measurement error from debris or oil film. Store gages in a protective case away from other metal tools to prevent nicking the gage surface. Handle with care to avoid dropping, which can alter the gage diameter and compromise accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.244 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (Decimal Inch)\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (mm)\u003c\/strong\u003e: 0.0002 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 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: 19-244-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51709577756978,"sku":"19-244-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f809de29956ac20c4aacc0b4e63c1f2b.jpg?v=1788458190","url":"https:\/\/voomisupply.com\/products\/spi-19-244-3-class-zz-minus-plug-pin-gage-0-244-in","provider":"Voomi Supply","version":"1.0","type":"link"}
