Manufactured from tool steel with a 10 microfinish surface, this gage measures 3.89 mm in diameter and carries a tolerance of 0.005 mm, meeting ASME B89.1 standards. Each unit ships with a Certificate of Accuracy that includes NIST traceability, making it suitable for documented inspection processes. Machinists, quality technicians, and calibration professionals rely on this type of gage for fast, repeatable go-type inspection of bored or drilled features.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in go inspection applications across manufacturing, tool and die, and precision machining shops. It is also suited for setting micrometers, verniers, and other measuring devices that require a certified reference. The 3.89 mm diameter makes it appropriate for small-bore inspection work where tight tolerances must be verified. It fits within standard gage-handle systems and is well-suited for both production floor use and calibration lab environments where NIST-traceable documentation is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance class: 0.005 mm tolerance for precise go inspection\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for consistent, repeatable contact with the bore\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance in production environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 standards for dimensional gaging\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.0000 inches for use with standard gage handles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard plug gage handles; also used directly for setting micrometers, verniers, and other measuring devices requiring a certified 3.89 mm reference.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists — no permanent installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel body. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece. Store in its protective case and re-certify on a schedule consistent 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: 3.89 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.005 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\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: 0.02 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: 112303890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51748100931890,"sku":"112303890","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97377d67f8de602224575e16d76fcef4_56b921f8-486b-4c55-afeb-0238a82fb8c8.jpg?v=1788889069","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112303890-class-zz-plus-plug-gage-3-89mm","provider":"Voomi Supply","version":"1.0","type":"link"}
