This gage measures 0.594 inches in diameter and is manufactured from steel for durability in shop and inspection environments. The minus tolerance designation means the gage is ground to the lower boundary of the nominal diameter, making it suitable for go\/no-go inspection work where dimensional accuracy is critical. Machinists, quality control inspectors, and tool-and-die technicians rely on Class ZZ gages for production inspection of drilled, reamed, or bored holes.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is appropriate for use in precision manufacturing, metal fabrication shops, and quality inspection departments. It fits standard gage handle holders sized for the 0.594-inch diameter range. Typical applications include verifying hole size conformance on machined components in automotive, aerospace, and general metalworking production environments where dimensional tolerances must be confirmed before assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance designation for lower-boundary hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.594-inch nominal diameter for accurate bore verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance in production environments\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.000200 inches for precise dimensional control\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard gage handle holders for the applicable diameter range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug gage for standard gage handle holders sized for the 0.594-inch diameter range, suitable for Class ZZ go\/no-go inspection applications in production and quality control settings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists and quality control inspectors following standard metrology practices. Clean the gage and the hole being inspected before use to prevent measurement errors caused by debris or burrs. Store the gage in a protective case away from other tooling to avoid surface damage that could affect accuracy. Periodic calibration against certified gage blocks is recommended to maintain measurement traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Minus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.594 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (Decimal Inch)\u003c\/strong\u003e: 0.000200 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\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: 19-594-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690658595122,"sku":"19-594-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2ba1de2f3843f5b4f303cff21e53d1a.jpg?v=1788273508","url":"https:\/\/voomisupply.com\/products\/spi-19-594-1-class-zz-minus-plug-pin-gage-0-594-in","provider":"Voomi Supply","version":"1.0","type":"link"}
