Manufactured from tool steel with a 10 microfinish surface coating, this gage checks that a hole diameter meets minimum acceptable size before the part moves to the next stage of production or assembly. The gage measures 4.93 mm in diameter with a tolerance of 0.00508 mm, and its overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy that carries full NIST traceability, satisfying documentation requirements for quality systems and audits.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for dimensional inspection in machine shops, toolrooms, and manufacturing cells where hole size must be verified to tight tolerances. It is commonly used alongside set micrometers, verniers, and other precision measuring devices as part of a go\/no-go inspection workflow. The Class ZZ Plus classification indicates a tighter tolerance than standard Class ZZ, making this gage appropriate for applications where dimensional accuracy is critical and measurement uncertainty must be minimized.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus classification with 0.00508 mm tolerance for tight-tolerance hole inspection\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface coating reduces friction and wear during repeated use\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.0000 inches for easy hand use in standard gage handles\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for quality system compliance\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B89.1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in go inspection applications with set micrometers, verniers, and other precision measuring devices where a 4.93 mm nominal hole diameter must be verified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, quality technicians, and toolroom personnel. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface. Clean the gage and the hole being inspected before each use to avoid false readings caused by chips, coolant, or debris. Do not force the gage into an undersized hole, as this can damage the gage surface and compromise its calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.93 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.00508 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\u003eClass\u003c\/strong\u003e: ZZ Plus\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\u003eApplication\u003c\/strong\u003e: Go Inspection, Set Micrometers, Verniers and Other Measuring Devices\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\u003eStandard\u003c\/strong\u003e: ASME B89.1\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: 112304930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51730418925874,"sku":"112304930","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7e2a647b3184ead6e2e73d5519ba705_2ff49491-2a22-42ce-9fdd-10f4fd388054.jpg?v=1788717111","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112304930-class-zz-plus-plug-gage-4-93mm","provider":"Voomi Supply","version":"1.0","type":"link"}
