Machined from tool steel with a 10 microfinish surface, this gage measures a nominal diameter of 4.77 mm with a tolerance of 0.005 mm, meeting the requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy that includes NIST traceability, confirming the measurement is backed by a documented calibration chain. It is sized for use with go inspection procedures and is compatible with setting micrometers, verniers, and other precision measuring devices.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for machine shops, quality control departments, and metrology labs that require repeatable, certified dimensional verification of small-diameter bores. Typical applications include go-gage inspection of drilled, reamed, or bored holes in the 4.77 mm range. The NIST-traceable certificate supports audit and ISO quality system documentation requirements. Licensed metrology technicians, toolmakers, and QC inspectors are the primary users of this gage in both production and inspection settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.77 mm nominal diameter with 0.005 mm tolerance for tight Class ZZ Plus accuracy\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for consistent, low-friction bore contact\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 dimensional gage standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for quality system compliance\u003c\/li\u003e\n  \u003cli\u003eSuitable for go inspection, setting micrometers, and vernier calibration use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of 4.77 mm diameter bores and for setting micrometers, verniers, and other precision measuring devices per ASME B89.1 requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and stored by metrology technicians and toolmakers following standard gage care procedures. Before use, clean the gage and bore contact surfaces to remove chips, oil, and debris that can cause false readings or premature wear. Do not force the gage through a bore; light, controlled insertion is required to avoid damaging the gage or the part. Store in a protective case away from heat sources to maintain dimensional stability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.77 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: 112304770\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51735845601586,"sku":"112304770","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c0e2e966b45b2513cf9b7c5dd09a18c_0e9cdf5f-3fbf-4699-9bad-1cdd62502cfc.jpg?v=1788774526","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112304770-class-zz-plus-plug-gage-4-77mm","provider":"Voomi Supply","version":"1.0","type":"link"}
