Measuring 21.34 mm in diameter with a tolerance of 0.005 mm (0.00508 mm nominal), this plug gage is manufactured from tool steel and finished to a 10 micro surface coating for consistent, repeatable contact. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for calibrated inspection records. Machining shops, quality control technicians, and metrology labs rely on this type of gage for fast, reliable go-type bore verification.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is intended for go inspection applications where confirming minimum acceptable bore size is required. It is compatible with use alongside set micrometers, verniers, and other precision measuring devices as a reference standard or functional check tool. Typical applications include incoming inspection, in-process quality checks on machined bores, and fixture verification in manufacturing environments. The gage conforms to ASME B89.1 standards, making it appropriate for facilities that require traceable, standards-based dimensional inspection tooling.\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 precise go inspection\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e10 micro surface finish coating for consistent gage contact\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for calibration documentation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 dimensional gage standards\u003c\/li\u003e\n  \u003cli\u003eCompact 2.0000-inch overall length suited for benchtop and floor inspection use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of 21.34 mm diameter bores and for use as a reference standard with set micrometers, verniers, and other precision measuring devices per ASME B89.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages of this type are handled by quality control technicians and metrology personnel, not installed in mechanical systems. Clean the gage and bore surfaces before use to prevent false readings caused by debris or oil film. Never force the gage into a bore; Class ZZ Plus gages are precision ground and forcing can cause damage to both the gage and the workpiece. Store in a protective case away from heat sources to maintain dimensional integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 21.34 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.005 mm (0.00508 mm nominal)\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: 0.32 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 Micro\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\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\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: 112121340\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51753764323634,"sku":"112121340","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_afcbb184-e2e5-4cff-a85d-4c1fc53a9027.jpg?v=1788940440","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112121340-class-zz-plus-plug-gage-21-34mm","provider":"Voomi Supply","version":"1.0","type":"link"}
