Built from steel with a 10 micro finish coating, this pin gage measures a nominal diameter of 21.72 mm with a tolerance of 0.00508 mm. It is used in NoGo inspection applications to verify that a hole or feature does not exceed its maximum allowable size. Each unit ships with a Certificate of Accuracy with NIST Traceability, making it suitable for use in calibrated inspection environments. Machinists, quality control technicians, and tool-and-die professionals are the primary installers and users of this gage.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for use in machine shops, production floor inspection stations, and metrology labs handling close-tolerance work. Its Class ZZ Minus designation makes it appropriate for NoGo functional inspection as well as for setting and checking micrometers, verniers, and other measuring devices. The 21.72 mm diameter and 2-inch overall length make it compatible with standard gage handle sets used in dimensional inspection workflows across general manufacturing and precision machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Minus tolerance classification for NoGo inspection applications\u003c\/li\u003e\n  \u003cli\u003e21.72 mm nominal diameter with 0.00508 mm tolerance for close-tolerance verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction with 10 micro surface finish for consistent contact and wear resistance\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST Traceability for calibrated inspection use\u003c\/li\u003e\n  \u003cli\u003e2-inch overall length compatible with standard plug gage handle sets\u003c\/li\u003e\n  \u003cli\u003eSuitable for setting micrometers, verniers, and other measuring devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard plug gage handle sets for NoGo inspection of machined bores and cylindrical features.

Insert the gage into a compatible handle before use and ensure hands are clean or gloves are worn to prevent corrosion from skin contact. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Do not force the gage into a bore; if resistance is encountered, verify the bore size with an alternate method before proceeding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 21.72 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\u003eGage Class\u003c\/strong\u003e: Class ZZ Minus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: NoGo Inspection, Setting 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: 0.33 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: 112221720\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51743813828914,"sku":"112221720","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_87f75d0b-20c6-4bf0-9151-8a539cdbd134.jpg?v=1788849939","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112221720-class-zz-minus-plug-pin-gage-21-72mm","provider":"Voomi Supply","version":"1.0","type":"link"}
