It measures to a nominal diameter of 0.841 inches with a tolerance of 0.0002 inches, making it appropriate for general-purpose inspection work where close but not master-grade accuracy is required. The steel construction provides durability through repeated use in shop and floor environments. Machinists, quality technicians, and tool-and-die professionals use this type of gage to verify that a machined feature falls within an acceptable dimensional range before a part moves to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eClass ZZ Plus plug gages are used in production and maintenance environments where standard-grade dimensional verification is needed. Typical applications include checking drilled, reamed, or bored holes in metal components, fixtures, and assemblies. This gage is suited for light-to-medium production inspection and is a common tool in machine shops, maintenance departments, and quality control stations working with steel and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.841 inches for direct hole inspection\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches meets Class ZZ Plus accuracy requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction resists wear through repeated gaging cycles\u003c\/li\u003e\n  \u003cli\u003eSingle-piece unit requires no additional components for standard use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for general-purpose dimensional inspection of machined holes at 0.841 inches nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and stored by dimensional inspection personnel, not installed in a system. Clean the gage and the hole being checked before use to prevent debris from affecting the reading. Do not force the gage through a hole — excessive insertion force can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.841 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 29-841-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697537155378,"sku":"29-841-4","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f32656ea9f2742d45aed1a48f550e30_8b26388a-4d5c-47e2-b435-e124e5a20f11.jpg?v=1788352584","url":"https:\/\/voomisupply.com\/products\/spi-29-841-4-class-zz-plus-plug-gage-0-841-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
