It measures a nominal diameter of 21.51 mm with a tolerance of 0.00508 mm (0.005 mm), making it suitable for Go inspection tasks where tight dimensional verification is required. Manufactured from tool steel with a 10 micro finish coating, this plug gage is a fixed-limit hand tool used by machinists, quality technicians, and metrologists to verify that a bored or reamed hole meets the lower acceptable limit of a given tolerance band. Each unit ships with a Certificate of Accuracy traceable to NIST.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in production inspection, incoming inspection, and calibration lab environments wherever hole diameter conformance must be verified against ASME B89.1 standards. Typical applications include Go inspection of machined bores, setting and verifying micrometers, verniers, and other measuring devices. It is appropriate for use in both shop floor and controlled metrology environments. The compact overall length of 2.0000 inches makes it easy to handle and store in standard gage storage systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade: 0.00508 mm tolerance for high-accuracy Go inspection\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for hardness and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003e10 micro surface finish coating resists wear and corrosion\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 dimensional gage standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for calibration documentation\u003c\/li\u003e\n  \u003cli\u003eCompact 2.0000-inch overall length for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for Go inspection of holes with a nominal diameter of 21.51 mm.

Store the gage in a protective case away from temperature extremes and contaminants that could affect dimensional accuracy. Clean the gage and the workpiece bore before use to prevent false readings or premature wear. Calibration intervals should be established per your facility quality system and the Certificate of Accuracy documentation supplied with the gage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 21.51 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: 0.32 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, Setting Micrometers, Verniers and Other Measuring Devices\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: 112321510\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51728594141490,"sku":"112321510","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_d564b172-667f-471c-adfb-6d76197469b1.jpg?v=1788693756","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112321510-class-zz-plus-plug-gage-21-51mm","provider":"Voomi Supply","version":"1.0","type":"link"}
