It checks whether a feature meets minimum size requirements, functioning as a go\/no-go reference tool on the shop floor or in an inspection environment. The gage measures 0.528 inches in diameter with a tolerance of 0.0002 inches, providing the accuracy expected for Class ZZ inspection work. At 0.2 pounds, it is lightweight enough for continuous hand use during production inspection cycles.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are standard tools in manufacturing quality control. This minus gage is suited for inspecting machined bores, drilled holes, and reamed features where dimensional conformance must be verified before assembly. Typical users include machinists, quality technicians, and tool-room personnel working in job shops, production facilities, or maintenance environments. The steel construction holds up to repeated use in standard shop conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance grade for general-purpose inspection work\u003c\/li\u003e\n  \u003cli\u003eMinus configuration checks minimum material condition of the feature\u003c\/li\u003e\n  \u003cli\u003e0.528 inch nominal diameter for direct bore verification\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for consistent, repeatable measurements\u003c\/li\u003e\n  \u003cli\u003eSteel construction resists wear during routine inspection use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for extended hand 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 in general-purpose bore inspection applications where a 0.528 inch nominal diameter reference is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by quality technicians and machinists and do not require installation in the traditional sense. Before use, clean both the gage and the feature being inspected to remove chips, oil, and debris that could affect readings. Handle the gage carefully to avoid dropping or impacting the precision-ground surface, as damage to the gage diameter will compromise measurement accuracy. Store the gage in a protective case when not in use to prevent corrosion and contact damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.528 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: Class ZZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Type\u003c\/strong\u003e: Minus Plug Pin Gage\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: 19-528-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720954544434,"sku":"19-528-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82b7d6a2158711fd7daaf07ce66a8b64.jpg?v=1788571414","url":"https:\/\/voomisupply.com\/products\/spi-19-528-9-class-zz-minus-plug-pin-gage-0-528-in","provider":"Voomi Supply","version":"1.0","type":"link"}
