Built from tool steel, this gage holds a tolerance of 0.0002 inches and features a 10 microfinish surface, ensuring consistent and repeatable measurement results. At 2.0 inches overall length, it is sized for practical bench and in-process use. Each unit ships with a Certificate of Accuracy with NIST traceability, supporting quality documentation requirements. Machinists, quality technicians, and inspection personnel rely on this type of gage to verify that bored, drilled, or reamed features fall within specified limits.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for go inspection applications in manufacturing and machine shop environments. It is also used to calibrate and set micrometers, verniers, and other precision measuring devices. Typical use scenarios include incoming inspection, in-process quality checks, and final part acceptance on components requiring tight hole-diameter control. The Class ZZ Plus designation indicates a tolerance grade appropriate for general-purpose inspection work where high accuracy and traceability are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.397 inches for precise hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable go\/no-go verification\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface finish minimizes wear and ensures accurate contact\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability in production and inspection environments\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for documentation and audit compliance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Class ZZ Plus plug gage for go inspection of 0.397-inch diameter holes and for setting micrometers, verniers, and other precision measuring devices per ASME B89.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages of this type are handled and used by quality technicians and machinists; no installation in the traditional sense applies. Before use, clean the gage and the workpiece bore to remove chips, oil, and debris that could affect measurement accuracy. Do not force the gage into an undersized hole, as this will damage the gage surface and compromise calibration. Store in a protective case away from heat sources and corrosive environments to maintain dimensional stability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.397 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\u003eTolerance\u003c\/strong\u003e: 0.0002 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\u003eApplication\u003c\/strong\u003e: Go 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\u003eStandard\u003c\/strong\u003e: ASME B89.1\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: 111139700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51744796770610,"sku":"111139700","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc5fd382dfcb07726f1e2418ce919e63_e0755eec-2730-4d10-8856-674d1245d125.jpg?v=1788860637","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111139700-class-zz-plus-plug-gage-0-397-in","provider":"Voomi Supply","version":"1.0","type":"link"}
