Manufactured from tool steel, this gage delivers a 10 microfinish surface and holds a tolerance of 0.00508 mm, making it suitable for precision dimensional verification in production and quality-control environments. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in calibrated inspection programs. Machinists, quality technicians, and tool room personnel rely on this type of gage to confirm that a drilled, reamed, or bored feature meets minimum size requirements before parts advance to the next operation.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in go inspection applications where confirming minimum hole size is critical. It is well suited for setting and verifying micrometers, verniers, and other measuring devices to a known reference diameter. Typical use cases include incoming inspection, in-process gauging on machined components, and calibration of measuring instruments in tool rooms and quality labs. The overall length of 2.0000 inches provides adequate handling clearance for most standard workpiece setups. Conforms to ASME B89.1 dimensional standards for gage blanks and tolerancing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.00508 mm for precise go inspection\u003c\/li\u003e\n  \u003cli\u003e8.4 mm nominal diameter, 2.0000 inch overall length\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for consistent, repeatable gaging contact\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style go plug gage for use with standard gage handle systems accepting 8.4 mm diameter gage blanks per ASME B89.1.

Clean both the gage and the part bore before inspection, and apply a light gage oil if repeated cycling is required to reduce wear. Do not force the gage into an undersized feature. Periodic recalibration against traceable standards is recommended to confirm gage integrity over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8.40 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\u003eTolerance\u003c\/strong\u003e: 0.00508 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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\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: 112108400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51742392779058,"sku":"112108400","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e4c23adefc96574e694d48b3ed338d_e2cc0594-8df5-43c2-9f84-48918c1e7af2.jpg?v=1788837170","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112108400-class-zz-plus-plug-gage-8-4-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
