Built from steel, it delivers a tolerance of 0.0002 inches on the minus side, making it suitable for production floor inspection and quality control applications. Machinists, toolmakers, and quality technicians use plug pin gages to verify hole size conformance without the need for complex measurement instruments. The Class ZZ designation indicates a working-grade gage appropriate for general inspection use rather than master or reference standards.\u003c\/p\u003e\n\u003cp\u003eThis gage is used in manufacturing and machining environments where hole diameter verification is part of routine production inspection. Typical applications include checking drilled, reamed, or bored holes in metal and plastic workpieces. It is appropriate for use in job shops, production facilities, and maintenance-repair-overhaul settings where fast, reliable go\/no-go checks are required. The minus tolerance means the gage is ground slightly undersize relative to the nominal diameter, following standard plug gage convention for go gages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ working-grade plug pin gage for production inspection use\u003c\/li\u003e\n  \u003cli\u003e0.326-inch nominal diameter for direct hole size verification\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance of 0.0002 inches for accurate undersize go-gage conformance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop floor environments\u003c\/li\u003e\n  \u003cli\u003eCompact single-pin format for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a working-grade go plug gage for general-purpose inspection of 0.326-inch nominal diameter holes in machined components across a wide range of materials and industries.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, inspect the gage surface for nicks or wear and verify calibration status per your quality management procedures. Store in a protective case away from other tooling to prevent surface damage. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.326 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (minus)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: Class ZZ\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: 19-326-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51717828378930,"sku":"19-326-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72656336bb09585d7e490de292ca92a4.jpg?v=1788546302","url":"https:\/\/voomisupply.com\/products\/spi-19-326-8-class-zz-minus-plug-pin-gage-0-326-in","provider":"Voomi Supply","version":"1.0","type":"link"}
