Plug pin gages are precision go\/no-go inspection tools used to verify bore diameter, hole size, and feature location in machined or fabricated components. The Class ZZ tolerance classification designates a minus condition, meaning the gage is manufactured to a tolerance of 0.0002 inches below nominal. This gage is designed for shop-floor and inspection-room use by machinists, quality control technicians, and tool-and-die professionals who require reliable dimensional verification without investing in higher-grade gage blocks or CMM equipment.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are typically applied in general-purpose inspection of production parts where hole diameter conformance must be confirmed quickly and repeatably. This gage is suited for use in light manufacturing, job shops, and maintenance environments where tolerance control on bored, drilled, or reamed holes is required. The steel construction provides durability for repeated use across standard production inspection cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.561-inch nominal diameter for precise bore and hole verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ classification with minus designation and 0.0002-inch tolerance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for shop-floor inspection use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity for individual replacement or addition to gage sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ minus plug pin gage for inspecting holes and bores with a nominal diameter of 0.561 inches in standard production and shop-floor inspection applications.\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 and do not require installation in a mechanical system. Gages should be cleaned and lightly oiled before and after use to prevent corrosion and maintain accuracy. Do not force the gage into a hole; insertion should be smooth and require minimal hand pressure. Store the gage in its protective case or on a clean, dry surface away from other tooling to prevent surface damage that could affect dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.561 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\u003c\/strong\u003e: 0.0002 inches\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: 19-561-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694514012466,"sku":"19-561-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c98164c21c0a81ad72e2b3ad8e6dcfa1.jpg?v=1788324864","url":"https:\/\/voomisupply.com\/products\/spi-19-561-0-class-zz-minus-plug-pin-gage-0-561-in","provider":"Voomi Supply","version":"1.0","type":"link"}
