It is designed to verify that a hole meets minimum acceptable diameter tolerances in a Go inspection workflow. The gage measures 6.99 mm in diameter and holds a tolerance of 0.00508 mm, making it suitable for close-tolerance production inspection. A 10 microfinish surface treatment reduces wear and ensures repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements of quality management systems. Machinists, tool-and-die makers, and quality technicians are the primary users of this gage.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in manufacturing, job shop, and inspection lab environments where hole diameter conformance must be verified before assembly. It is well suited for Go inspection of workpieces produced on CNC machining centers, drill presses, and boring mills. The gage is also referenced when calibrating or verifying the accuracy of micrometers, verniers, and other dimensional measuring devices. Its compact form factor and 0.04-pound weight make it easy to handle during high-volume part inspection. Conformance to ASME B89.1 ensures it meets recognized national standards for plain plug gages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance classification for Go inspection applications\u003c\/li\u003e\n  \u003cli\u003e6.99 mm diameter with 0.00508 mm tolerance for close-tolerance hole verification\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for repeatable, low-wear contact\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 standard for plain plug gages\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for Go inspection of 6.99 mm nominal diameter holes.

Store the gage in its case when not in use to prevent nicks and corrosion on the precision ground surface. Never force the gage into a hole; if resistance is felt beyond normal light hand pressure, the hole is undersize or contains burrs that must be addressed before re-gauging. Clean the gage and workpiece contact surfaces before each use to prevent measurement error from chips or coolant residue.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 6.99 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\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\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: 0.04 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: 112306990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51739773796658,"sku":"112306990","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e88df3d88469d3737f2848989bbcd906_7a98bec6-3d85-4dee-9316-ddd196565e32.jpg?v=1788818704","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112306990-class-zz-plus-plug-gage-6-99-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
