It measures 0.426 inches in diameter and is manufactured from steel for consistent dimensional stability under shop-floor conditions. The minus tolerance configuration means the gage is made to the low side of the nominal diameter, following standard GO\/NO-GO gage practice. With a tolerance of 0.0002 inches, this gage is suited for checking machined holes where tight dimensional control is required. Machinists, quality technicians, and tool-room professionals use plug pin gages as part of standard dimensional verification procedures.\u003c\/p\u003e\n\u003cp\u003eThis gage is appropriate for use in manufacturing, machine shop, and quality assurance environments where hole diameter conformance must be verified to close tolerances. It is a hand-held, single-diameter inspection tool used in conjunction with gage blocks, ring gages, or other reference standards in a complete inspection program. Typical applications include checking drilled, reamed, or bored holes in metal components across general machining and precision manufacturing operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.426 inch nominal diameter for direct hole inspection at that size\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance class — the standard commercial-grade class for plug gages\u003c\/li\u003e\n  \u003cli\u003eMinus configuration — manufactured to the low side of nominal for proper GO gage practice\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for reliable close-tolerance inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for dimensional stability and wear resistance in shop use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece plug gage format — no assembly required, ready for immediate use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage for use with compatible gage handle sets in dimensional inspection of machined holes at 0.426 inch nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by quality technicians or machinists — no power tools or utilities need to be shut down for inspection use. Store gages in a protective case away from moisture to prevent corrosion on the steel body. Clean and lightly oil the gage after use following standard metrology handling practices. Calibrate or verify against a traceable reference standard at intervals appropriate to your facility's quality management program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.426 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\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\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: 19-426-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51717585633586,"sku":"19-426-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57b46828202f09664aa3e5bd13e55719.jpg?v=1788542928","url":"https:\/\/voomisupply.com\/products\/spi-19-426-6-class-zz-minus-plug-pin-gage-0-426-in","provider":"Voomi Supply","version":"1.0","type":"link"}
