It measures a nominal diameter of 4.95 mm with a tolerance of 0.00508 mm, giving inspectors a reliable go-gage reference for verifying bore dimensions to ASME B89.1 standards. The gage body is manufactured from tool steel and features a 10 microfinish surface, which reduces measurement error and wear during repeated use. Installation and use require no specialized power tools, making it a straightforward addition to any inspection workflow.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for go inspection applications across light manufacturing, precision machining, and dimensional metrology setups. It is compatible with use alongside set micrometers, verniers, and other calibrated measuring devices where a traceable reference standard is required. Each unit ships with a Certificate of Accuracy with NIST traceability, supporting documentation requirements for ISO and AS9100 quality management systems. Typical users include QC inspectors, machinists, and metrology technicians working in both production and tool room settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.00508 mm for high-accuracy go inspection\u003c\/li\u003e\n  \u003cli\u003e4.95 mm nominal diameter, tool steel construction for wear resistance\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface finish minimizes gage wear and measurement deviation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.0000 inches for easy hand-held use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as a go inspection gage and as a reference standard with set micrometers, verniers, and other measuring devices requiring a traceable plug gage in the 4.95 mm diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages require no installation in the traditional sense but should be handled and stored according to standard metrology practices to preserve surface finish and dimensional integrity. Clean the gage and the bore being inspected before use to prevent false readings caused by debris or contamination. Do not force the gage into an undersized bore, as this will damage both the gage and the workpiece. Periodic recalibration against traceable standards is recommended to maintain measurement confidence over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.95 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\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\u003eSurface Finish\u003c\/strong\u003e: 10 Microfinish\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: 112304950\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51740598010162,"sku":"112304950","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7e2a647b3184ead6e2e73d5519ba705_beb8a408-af98-42e8-bdbf-368a2b7aa151.jpg?v=1788826108","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112304950-class-zz-plus-plug-gage-4-95-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
