It checks whether a hole meets its minimum size requirement, confirming the part will accept a mating component. The gage measures a nominal diameter of 20.1 mm with a tolerance of 0.005 mm, making it suitable for close-tolerance inspection work. A 10 microfinish surface finish reduces wear and maintains dimensional integrity over repeated use. Supplied with a Certificate of Accuracy carrying NIST traceability, it meets ASME B89.1 standards. Machinists, quality technicians, and tool-room inspectors use this gage in production and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in machine shops, manufacturing facilities, and quality control labs where hole diameter verification is required. It is appropriate for go inspection applications and can also be used to set micrometers, verniers, and other measuring devices to a known reference diameter. The 20.1 mm size targets metric hole tolerances common in precision component manufacturing. With an overall length of 2.0 inches, it fits standard gage handle setups and benchtop inspection routines. Its tool steel construction and 10 microfinish coating hold up under regular production-floor use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating with 0.005 mm tolerance for close-tolerance go inspection\u003c\/li\u003e\n  \u003cli\u003eTool steel construction with 10 microfinish surface for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eNominal diameter of 20.1 mm for metric hole verification\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 standards for dimensional gaging\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard plug gage handles for flexible use across inspection setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as a go inspection gage for 20.1 mm diameter holes and as a reference standard for setting micrometers, verniers, and other measuring devices.

Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage through a hole; go gages should pass under light hand pressure only. Store in a protective case away from temperature extremes to maintain dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 20.1 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: 2.0 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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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\u003eStandards\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: 0.28 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: 112120100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51732406599986,"sku":"112120100","price":20.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_3bdafe28-f495-4ad0-8a0e-19ace7d40e7d.jpg?v=1788742466","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112120100-class-zz-plus-plug-gage-20-1mm","provider":"Voomi Supply","version":"1.0","type":"link"}
