Built to Class ZZ Plus tolerances of 0.0002 inches, this go\/no-go style gage allows technicians and machinists to verify that a 0.218-inch diameter hole or bore meets dimensional specifications. The steel construction provides durability for repetitive use in production or inspection settings. Weighing 0.2 pounds, it is compact and easy to handle during routine measurement tasks.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used wherever tight-tolerance hole verification is required, including machined components, fabricated assemblies, and production floor inspection stations. It is suited for both job shop environments and higher-volume manufacturing lines where consistent dimensional verification of 0.218-inch diameter features is part of the quality process. Machinists, quality technicians, and metrologists are the primary users of this type of gage.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for precise dimensional verification\u003c\/li\u003e\n  \u003cli\u003eNominal measurement diameter of 0.218 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production and inspection use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand operation\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suitable for individual tooling procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-procurement plug gage for use in standard Class ZZ Plus gage applications requiring a 0.218-inch nominal diameter measurement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Store the gage in its protective case when not in use to avoid damage to the precision-ground surface. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece. Periodic recalibration against a traceable standard is recommended to maintain measurement accuracy over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.218 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: 29-218-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51723886788914,"sku":"29-218-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56fabd4db1fb96de270679dfdd5ed621.jpg?v=1788609361","url":"https:\/\/voomisupply.com\/products\/spi-29-218-5-class-zz-plus-plug-gage-0-218-in-diameter","provider":"Voomi Supply","version":"1.0","type":"link"}
