It measures 4.78 mm in diameter with a tolerance of 0.005 mm, making it suitable for precise go inspection of bored holes, machined ports, and dimensional check points. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets ASME B89.1 standards. Machinists, quality technicians, and tool room personnel use this gage for fast, repeatable attribute inspection in production and metrology environments.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in go inspection applications where a machined hole or bore must be verified against a tight dimensional tolerance. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices that require a known-diameter reference. The 4.78 mm size targets small-bore work common in precision machined components, hydraulic fittings, and instrument bodies. Suitable for both shop floor and inspection room use in light manufacturing, aerospace, and general metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.78 mm diameter with 0.005 mm tolerance for tight go inspection work\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for consistent, low-wear contact with the work piece\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability in repeated-use inspection cycles\u003c\/li\u003e\n  \u003cli\u003eComplies with ASME B89.1 dimensional gage standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003e2.0000 inch overall length suits standard gage handle holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision gage for use with standard plug gage handles and gage block accessories.

Store the gage in its case when not in use to prevent surface damage and protect the calibrated diameter. Avoid dropping or stacking with other metal tools, as impact can alter the gage diameter and invalidate NIST traceability. Re-verify certification status periodically according to your facility's gage calibration program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.78 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: 112104780\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51734733160754,"sku":"112104780","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c0e2e966b45b2513cf9b7c5dd09a18c_2fe9fddf-0b28-4737-b973-62481d6e71ab.jpg?v=1788766296","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112104780-class-zz-plus-plug-gage-4-78-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
