Built from tool steel with a 10 microfinish surface, this gage provides a reliable go-inspection reference for holes near the 7.97 mm nominal diameter. The 0.005 mm (0.00508 mm actual) tolerance class makes it suitable for moderate-precision fits where repeatable, traceable measurement is required. Each unit ships with a Certificate of Accuracy that carries NIST traceability, supporting documented quality programs and audit requirements. Licensed metrologists, machinists, and quality technicians routinely use this type of gage as part of a calibrated inspection routine.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in go-inspection applications to verify that a bored, drilled, or reamed hole meets minimum size requirements before assembly. It also serves as a setting standard for micrometers, verniers, and other variable measuring devices that need a physical reference at or near 7.97 mm. Typical environments include precision machining, toolroom inspection, and incoming material verification. The compact overall length of 2.0000 inches allows use in shallow or restricted bore depths. Both production floor inspectors and metrology lab staff will find this gage appropriate for daily use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.005 mm supports moderate-precision go inspection\u003c\/li\u003e\n  \u003cli\u003eTool steel construction provides wear resistance for repetitive inspection cycles\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface finish ensures consistent, low-drag contact in the bore\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for documented QC programs\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 standards for plain plug gages\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.0000 inches suits shallow bore applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go-inspection of holes with a 7.97 mm nominal diameter and for use as a setting reference with micrometers, verniers, and other measuring devices requiring a traceable physical standard at this diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and deployed by machinists, quality technicians, and metrologists — no power source or mechanical installation is required. Store the gage in its protective case when not in use and avoid contact with abrasive surfaces that could alter the finish. Clean the gage and the bore being inspected before use to prevent debris from affecting the reading or damaging the gage surface. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity in accordance with your quality management system requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7.97 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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: 10 Microfinish\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\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: VERMONT GAGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 112307970\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51750043255090,"sku":"112307970","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e4c23adefc96574e694d48b3ed338d_037019f2-4b2d-4998-91ec-8f7944340da3.jpg?v=1788913339","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112307970-class-zz-plus-plug-gage-7-97mm","provider":"Voomi Supply","version":"1.0","type":"link"}
