It measures a nominal diameter of 0.022 inches with a tolerance of 0.0002 inches, making it suitable for close-tolerance inspection work where dimensional accuracy is critical. Constructed from steel for durability and wear resistance, this plug gage is a go\/no-go style instrument used by machinists, toolmakers, and quality inspectors to confirm that drilled, reamed, or bored holes fall within specification.\u003c\/p\u003e\n\u003cp\u003eThis gage is appropriate for use in precision manufacturing environments, including job shops, production floors, and inspection labs. Class ZZ Plus gages are typically used for inspection of parts requiring tighter dimensional control than standard commercial tolerances. The compact size of this 0.022-inch gage makes it well suited for small-diameter hole verification on close-tolerance components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.022 inches for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for close-tolerance verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy bench or field use\u003c\/li\u003e\n  \u003cli\u003eSold individually — one gage per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a go\/no-go inspection tool for small-diameter holes in precision-machined components requiring a 0.022-inch nominal bore diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, toolmakers, and quality-control technicians. Store gages in a protective case when not in use to prevent damage to the precision ground surfaces. Clean the gage and the hole being measured before inspection to ensure accurate readings. Do not force the gage into a hole — resistance indicates the hole is undersize or contains debris.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.022 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\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: 29-022-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51711589712178,"sku":"29-022-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d65e36ded96bf3829a4525ae3fcb7de2.jpg?v=1788477314","url":"https:\/\/voomisupply.com\/products\/spi-29-022-1-class-zz-plus-plug-gage-0-022-in","provider":"Voomi Supply","version":"1.0","type":"link"}
