It measures 21.7 mm in diameter and is manufactured from tool steel for long service life and dimensional stability. The gage carries a 0.005 mm (0.00508 mm actual) tolerance and a 10 microfinish surface, making it suitable for Go inspection work where accurate internal diameter verification is required. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented inspection processes. It meets ASME B89.1 standards.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in machine shops, inspection departments, and manufacturing environments where internal bore dimensions must be verified to close tolerances. It is appropriate for use as a Go gage in qualifying machined bores and is also compatible with setup and calibration of micrometers, verniers, and other precision measuring devices. Typical users include machinists, quality control technicians, and metrology professionals working in both production and tool room settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21.7 mm diameter with 0.005 mm tolerance for precise Go inspection\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for accurate, repeatable contact with bore walls\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for documented QC processes\u003c\/li\u003e\n  \u003cli\u003eCompatible with setting micrometers, verniers, and other precision measuring devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for Go inspection of 21.7 mm diameter bores.

Before use, clean the gage and the bore being inspected to remove debris, oil, or chips. Apply light gage oil when inserting into bores to reduce wear on the gage surface. Inspection work should be performed by qualified personnel following applicable shop or laboratory calibration procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 21.7 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.00508 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: 10 Microfinish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B89.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Certificate of Accuracy with NIST Traceability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 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: VERMONT GAGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 112121700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51729263788338,"sku":"112121700","price":22.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_10176dac-c0ac-46ac-8d05-c13b797df815.jpg?v=1788702297","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112121700-class-zz-plus-plug-gage-21-7mm","provider":"Voomi Supply","version":"1.0","type":"link"}
