It measures 4.86 mm in diameter with a tolerance of 0.005 mm (0.00508 mm actual), making it suitable for go-type inspection work where tight dimensional control is required. Constructed from tool steel with a 10 microfinish coating, this gage provides repeatable, reliable readings over extended service life. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for calibrated tooling in quality-controlled environments. Machinists, quality technicians, and metrology lab personnel are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in manufacturing, machine shop, and inspection environments where hole diameter verification is part of standard process control. It is well suited for go-inspection routines and for setting or verifying micrometers, verniers, and other measuring devices. The 4.86 mm diameter fits applications involving small-bore precision features common in aerospace, automotive, and general mechanical fabrication. Its compact overall length of 2 inches allows use in confined fixture setups and on standard gage handle assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade: 0.005 mm, suitable for go-type dimensional inspection\u003c\/li\u003e\n  \u003cli\u003eTool steel construction with 10 microfinish surface coating for durability and accurate seating\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable Certificate of Accuracy included with each unit\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.0 inches fits standard plug gage handles and fixture setups\u003c\/li\u003e\n  \u003cli\u003eSuitable for setting micrometers, verniers, and other precision measuring devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard plug gage handle assemblies and compatible with go-inspection routines per ASME B89.1.

Store in a protective case away from abrasive surfaces and temperature extremes. Before use, verify the gage is clean and free of burrs or debris that could affect seating. Calibrated tooling should be recertified at intervals consistent with your facility quality plan and applicable metrology standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.86 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.005 mm (0.00508 mm actual)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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\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: 112104860\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51743998345522,"sku":"112104860","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7e2a647b3184ead6e2e73d5519ba705_2b83bd4b-e4cc-48a8-84ce-5ebdd28c8699.jpg?v=1788852648","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112104860-class-zz-plus-plug-gage-4-86mm","provider":"Voomi Supply","version":"1.0","type":"link"}
