At 21.38 mm in diameter with a tolerance of 0.00508 mm, this gage delivers the precision required for NoGo inspection work. The overall length is 2 inches, keeping the gage compact and easy to handle at a workbench or on the production floor. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming the gage has been verified against national measurement standards. Machinists, quality technicians, and metrology professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is suited for NoGo inspection tasks in manufacturing and quality control environments. It is used alongside set micrometers, verniers, and other precision measuring devices to confirm that hole diameters stay within specified tolerances. The Class ZZ designation identifies this as a general-purpose inspection grade appropriate for production-line checking where commercial-grade accuracy is required. Typical applications include incoming inspection, in-process quality checks, and final acceptance verification of machined holes in metal or plastic components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Minus designation for NoGo inspection of hole diameters\u003c\/li\u003e\n  \u003cli\u003e21.38 mm measurement diameter with 0.00508 mm tolerance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e2-inch overall length for compact, bench-friendly handling\u003c\/li\u003e\n  \u003cli\u003e10 Micro coating finish for surface protection and smooth insertion\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST Traceability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with set micrometers, verniers, and other precision measuring devices requiring a 21.38 mm Class ZZ Minus NoGo plug gage reference.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis gage is handled and used by quality technicians and machinists in inspection settings, not installed in a mechanical system. Store the gage in its protective case when not in use to prevent surface damage or dimensional change. Do not force the gage into a feature; light hand pressure only is appropriate for plug gage inspection work. Clean contact surfaces before use to prevent contamination from affecting measurement results.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 21.38 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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: 10 Micro\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: NoGo 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\u003eWeight\u003c\/strong\u003e: 0.32 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: 112221380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51743327355186,"sku":"112221380","price":24.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_91b10a2f-8877-4801-adfc-a0200d51e20b.jpg?v=1788845689","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112221380-class-zz-minus-plug-pin-gage","provider":"Voomi Supply","version":"1.0","type":"link"}
