Built from tool steel with a 10 microfinish surface, this gage provides a measurement diameter of 0.31 inches and holds a tolerance of 0.0002 inches. It ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. Machinists, quality control technicians, and toolroom personnel use this gage to verify hole diameter acceptance during in-process and final inspection. Its compact form factor suits bench inspection stations and field-side use.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for go inspection applications in manufacturing, machining, and precision assembly environments. It is also used to set and verify micrometers, verniers, and other measuring devices where a known reference diameter is required. The 0.31-inch diameter and 2.0-inch overall length make it a practical choice for small-bore inspection work in both job shop and production settings. A single unit is packaged per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement diameter of 0.31 inches with a tolerance of 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus classification meeting ASME B89.1 standards\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for accurate, repeatable 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\u003eSuitable for setting micrometers, verniers, and other measuring instruments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of holes at 0.31 inches nominal diameter; also used as a reference standard to calibrate and set micrometers, verniers, and comparable hand-measuring devices.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled and stored by qualified inspection or toolroom personnel. Clean the gage and workpiece bore before use to prevent debris from affecting readings or damaging the gage surface. Do not force the gage through an undersized hole, as this will cause wear and dimensional deviation. Store in the provided case or a protected location away from moisture to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 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\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: 111131000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51750667485490,"sku":"111131000","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e4c23adefc96574e694d48b3ed338d_8dbcc226-5035-4d36-9c50-b031a76c3e6f.jpg?v=1788918122","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111131000-class-zz-plus-plug-gage-0-31-in","provider":"Voomi Supply","version":"1.0","type":"link"}
