Built from steel, this go\/no-go style gage gives machinists and quality control technicians a fast, reliable method for checking bore size to a tolerance of 0.0002 inches. Class ZZ Plus gages meet standard go-plug tolerance classifications and are suited for production inspection where consistent, repeatable measurement is required. Weighing 0.2 pounds, the gage is compact and easy to handle at the inspection bench or on the shop floor.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in manufacturing and machining environments to confirm that drilled, reamed, or bored holes fall within specified dimensional limits. It is appropriate for inspection of steel, aluminum, and other common workpiece materials where hole size acceptance or rejection must be documented. Quality technicians, tool room machinists, and precision metrology staff are the primary users of this type of gage in both job shop and production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.222 inch nominal diameter for precise hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance meets Class ZZ Plus classification standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 0.2 pounds for easy bench or floor use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity for individual procurement flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard inspection tool for applications requiring Class ZZ Plus plug gage verification at 0.222 inches nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, quality technicians, and tool room personnel — no special installation is required. Store the gage in a protective case away from moisture and temperature extremes to preserve dimensional accuracy. Clean the gage and workpiece bore before use to prevent debris from causing false readings. Never force a plug gage into an undersized hole, as this can damage the gage surface and compromise 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: 0.222 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  \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: 29-222-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721783574834,"sku":"29-222-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2988888bbb9f3ebbd79280023371e7bc.jpg?v=1788580751","url":"https:\/\/voomisupply.com\/products\/spi-29-222-7-class-zz-plus-plug-gage-0-222-in-diameter","provider":"Voomi Supply","version":"1.0","type":"link"}
