Built to a tolerance of 0.0002 inches, this gage checks hole diameter conformance at 0.868 inches. The steel construction provides durability for repeated use on the shop floor or in a quality control setting. Class ZZ Plus gages are used in go\/no-go inspection workflows to verify that drilled, reamed, or bored holes fall within specified dimensional limits. Machinists, toolroom technicians, and quality inspectors rely on this type of gage for fast, repeatable in-process and final inspection checks.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in manufacturing, toolroom, and metrology lab environments where hole diameter verification is required. It applies to ferrous and non-ferrous workpieces across a range of industries including general machining, aerospace component inspection, and precision fabrication. The 0.868-inch nominal diameter makes it a direct fit for inspection of correspondingly sized bores.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating at 0.0002 inches for high-accuracy bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.868-inch nominal measurement diameter\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and resistance to wear during repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling during inspection\u003c\/li\u003e\n  \u003cli\u003eDesigned for go\/no-go inspection workflows in production and toolroom settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision inspection tool for verifying 0.868-inch diameter bores in machined components.

Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain accuracy. Do not force the gage into an undersized bore, as this can damage the gage and compromise its calibration. Store in a protective case away from heat sources and abrasive materials to preserve tolerance integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.868 inches\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  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 29-868-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696334471474,"sku":"29-868-7","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6f6c0015b2737fcf76a7251c5854a12.jpg?v=1788341596","url":"https:\/\/voomisupply.com\/products\/spi-29-868-7-class-zz-plus-plug-gage-0-868-in","provider":"Voomi Supply","version":"1.0","type":"link"}
