This single-ended pin gage is used to verify that a bore or hole does not exceed its maximum allowable size, confirming the part falls within tolerance. At 2 inches in overall length and weighing 0.015 pounds, it is a compact, hand-held tool built from steel with a 10 microfinish surface coating. Each unit ships with a Certificate of Accuracy that includes NIST traceability, satisfying quality documentation requirements common in manufacturing and inspection environments. Machinists, quality technicians, and metrology professionals are the primary users of this gage.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for NoGo inspection of holes and bores in production and quality-control settings. It can also be used to set micrometers, verniers, and other measuring devices that require a known reference diameter. The 0.0002-inch tolerance rating places it within Class ZZ specifications, making it appropriate for general-purpose inspection where that tolerance class is specified. Typical applications include incoming inspection, in-process checks on machined components, and calibration support for handheld measuring instruments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Minus designation — built for NoGo inspection to confirm holes do not exceed maximum allowable size\u003c\/li\u003e\n  \u003cli\u003e0.2100-inch diameter with a 0.0002-inch tolerance for reliable, repeatable measurement\u003c\/li\u003e\n  \u003cli\u003eSteel construction with 10 microfinish surface for dimensional stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003e2-inch overall length provides a secure grip during single-handed inspection tasks\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability to support quality documentation and audit requirements\u003c\/li\u003e\n  \u003cli\u003eSuitable for setting micrometers, verniers, and other precision measuring devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ Minus plug pin gage for use in NoGo bore and hole inspection, and for referencing micrometers, verniers, and similar precision measuring instruments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHandle this gage with clean, dry hands or cotton inspection gloves to prevent corrosion and dimensional distortion from skin oils and moisture. Insert the pin gage into the bore with a smooth, axial motion — do not force or rotate aggressively, as this will cause premature wear and affect accuracy. Store the gage in its protective case when not in use, away from temperature extremes that could cause thermal expansion errors. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.2100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Minus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: 10 Microfinish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\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: 111221000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51731277218098,"sku":"111221000","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/529821f9205ec0e25c5a3cbde2145991_7ebf02b8-723c-4ea2-8085-222ba1581912.jpg?v=1788729165","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111221000-class-zz-minus-plug-pin-gage-0-21-in","provider":"Voomi Supply","version":"1.0","type":"link"}
