Manufactured from tool steel with a 10 microfinish surface, this gage delivers consistent, reliable results when checking whether a hole meets its minimum acceptable diameter. The measuring diameter is 0.4375 inches with a tolerance of 0.0002 inches, conforming to ASME B89.1. Each unit ships with a Certificate of Accuracy that carries NIST traceability, satisfying documentation requirements in calibrated inspection environments. Machinists, quality technicians, and metrology professionals use this gage as part of standard go\/no-go inspection routines.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in production inspection, incoming quality control, and calibration lab settings. Its 0.4375-inch diameter makes it appropriate for checking 7\/16-inch nominal bores in metalworking, toolroom, and precision manufacturing applications. The gage also serves as a setting standard for micrometers, verniers, and other measuring devices where a known physical reference is required. The 2.0-inch overall length provides adequate grip and handling for bench inspection work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance at 0.0002 inches per ASME B89.1\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for consistent contact and minimal wear on precision bores\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for hardness and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for audit and calibration records\u003c\/li\u003e\n  \u003cli\u003eUsable as a setting reference for micrometers, verniers, and comparable measuring instruments\u003c\/li\u003e\n  \u003cli\u003eCompact 2.0-inch overall length suited for bench and in-process inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of features with a 0.4375-inch nominal diameter.

Store the gage in its case when not in use and allow it to thermally stabilize to the inspection environment before use, particularly in temperature-controlled metrology labs. Periodic recalibration intervals should be established per the facility quality plan in accordance with ASME B89.1 and applicable quality system requirements. Do not force the gage into a bore; hand insertion with light axial pressure is the correct technique.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: 10 Microfinish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\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: 111343750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51746176860466,"sku":"111343750","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dacb2a1cc7f03d61c8c97e4621fd522a_0446b9d9-7e67-482f-af76-e5759564d9f8.jpg?v=1788866766","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111343750-class-zz-plus-plug-gage-0-4375-in","provider":"Voomi Supply","version":"1.0","type":"link"}
