Built from steel, this go\/no-go style gage gives machinists, toolmakers, and quality control technicians a fast, reliable method for checking hole conformance on the shop floor or in an inspection environment. Class ZZ is the standard for production plug gages used in general-purpose inspection work, and the Plus designation indicates the gage is made to the upper half of the tolerance band, extending service life.\u003c\/p\u003e\n\u003cp\u003eThis gage is used wherever precise bore verification is required in metal fabrication, machining, and manufacturing inspection settings. It is suited for checking drilled, reamed, or honed holes in production parts where dimensional control to within a few ten-thousandths of an inch is critical. Typical users include CNC machinists, QC inspectors, and toolroom technicians working to ASME or comparable dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.199 inch nominal diameter for precise small-bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for tight dimensional control\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus designation extends gage life by using the upper tolerance half\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production environments\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ Plus plug gage for verifying 0.199 inch nominal bore diameters in standard production inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and stored by metrology or quality control personnel following standard gage-handling practices. Always clean the bore and gage surfaces before use to prevent debris from affecting the reading or damaging the gage. Store in a protective case away from heat sources to prevent thermal expansion errors. Periodic calibration against a certified master is recommended to maintain traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.199 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\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: 29-199-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51702663971122,"sku":"29-199-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be570af115f2dcfbf21c5351b4b41827.jpg?v=1788412626","url":"https:\/\/voomisupply.com\/products\/spi-29-199-7-class-zz-plus-plug-gage-0-199-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
