It measures hole diameters at a nominal 4.55 mm with a tolerance of 0.00508 mm, giving inspectors and machinists a reliable go-condition reference. The ground and lapped gaging surface carries a 10 microfinish rating, which ensures repeatable, low-friction contact with the workpiece bore. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements in quality-controlled shops and manufacturing environments. Licensed metrology technicians, toolroom machinists, and quality inspectors are the primary users of this gage.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for incoming inspection, in-process verification, and final acceptance of precision bores in residential and commercial manufacturing settings. Typical applications include checking drilled, reamed, or bored holes during machining operations, and setting or verifying micrometers, verniers, and other measuring devices to a known reference diameter. The 2.0000-inch overall length fits standard handle holders. It is appropriate for any shop or inspection department working to ASME B89.1 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.00508 mm for precision go-condition inspection\u003c\/li\u003e\n  \u003cli\u003e10 microfinish ground surface for consistent, low-wear contact\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for hardness and long service life\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 dimensional gaging standards\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.0000 inches fits standard plug gage handles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a go-inspection plug gage for use with standard gage handle holders and compatible with micrometers, verniers, and other measuring devices requiring a 4.55 mm reference standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by metrology technicians and quality inspectors rather than installed in the traditional sense. Before use, clean the gage and the workpiece bore with a lint-free cloth to remove chips, oil, and debris that could affect the reading. Apply light gage oil to the gaging surface to reduce wear during insertion. Store the gage in its protective case when not in use to prevent nicks or corrosion that would invalidate the NIST-traceable calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.55 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\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: 112304550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51730519687474,"sku":"112304550","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c0e2e966b45b2513cf9b7c5dd09a18c_78e983bb-96b7-40d7-83f5-293c08e54737.jpg?v=1788718873","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112304550-class-zz-plus-plug-gage-4-55-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
