It is used to verify that a bored or reamed hole does not exceed its maximum allowable size, functioning as the NoGo member in a go\/no-go inspection pair. The gage is manufactured from steel and includes a Certificate of Accuracy with NIST traceability, making it suitable for calibrated inspection environments. Overall length is 2 inches. It is installed and used by quality control technicians, machinists, and tool-room personnel performing dimensional inspection on production parts.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is applied in NoGo hole inspection routines where confirming maximum material condition is required. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a traceable reference standard. Typical applications include inspection of machined bores in manufacturing, job shop, and quality lab environments where close-tolerance hole verification is part of the process. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general production inspection rather than master or working reference standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Minus tolerance class for NoGo hole inspection\u003c\/li\u003e\n  \u003cli\u003e18.34 mm measurement diameter with 0.00508 mm tolerance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCertificate of Accuracy with NIST traceability included\u003c\/li\u003e\n  \u003cli\u003eCompatible with setting micrometers, verniers, and other measuring devices\u003c\/li\u003e\n  \u003cli\u003e2-inch overall length for standard hand-held use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for NoGo inspection of holes at 18.34 mm diameter and for setting micrometers, verniers, and other measuring devices requiring a traceable reference at this diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are used by hand and do not require tools for operation, but they should be handled with clean, dry gloves or a gage holding fixture to prevent corrosion from skin contact. Store the gage in its case when not in use and keep it away from magnetic fields and abrasive surfaces. Re-calibrate periodically according to your quality management system requirements, using the included NIST-traceable certificate as the baseline reference.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 18.34 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\u003eIncludes\u003c\/strong\u003e: Certificate of Accuracy with NIST Traceability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: 112218340\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51739945566514,"sku":"112218340","price":18.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_81c4f83d-3af4-430a-956b-7a09f8955c4d.jpg?v=1788820618","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112218340-class-zz-minus-plug-pin-gage-18-34mm","provider":"Voomi Supply","version":"1.0","type":"link"}
