Built from steel, this go\/no-go style gage provides a tolerance of 0.0002 inches, meeting the requirements of Class ZZ Plus standards for general-purpose inspection work. It is used in quality control and machining environments where hole size verification is a routine part of the production or maintenance workflow. Machinists, toolmakers, and quality inspection technicians are the primary users of this type of gage.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for shop-floor and inspection bench use in manufacturing, fabrication, and precision machining settings. It is appropriate for checking drilled, bored, or reamed holes in both production runs and one-off part verification tasks where a 0.485-inch nominal hole diameter is specified. The gage is a standard single-piece unit with a package quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.485-inch nominal measurement diameter for direct hole verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for general-purpose inspection accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under shop conditions\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling during inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for individual or low-volume procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug gage for inspection of holes with a 0.485-inch nominal diameter in general-purpose machining and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality technicians following standard metrology practices. Store and handle the gage carefully to prevent surface damage that could affect measurement accuracy. Clean the gage and the hole being measured before use to remove chips, burrs, or contaminants. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.485 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: 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\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: 29-485-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51711732220210,"sku":"29-485-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b6df5a6cf07f50175e94dc6ab414d57.jpg?v=1788479001","url":"https:\/\/voomisupply.com\/products\/spi-29-485-0-class-zz-plus-plug-gage-0-485-in","provider":"Voomi Supply","version":"1.0","type":"link"}
