It measures 0.388 inches in diameter with a tolerance of 0.0002 inches, making it suitable for Go inspection applications where tight dimensional control is required. Constructed from tool steel with a 10 microfinish surface, this gage delivers consistent, repeatable measurement performance. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming compliance with ASME B89.1 standards. Licensed machinists, quality technicians, and calibration professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in production and inspection environments where bore diameters must be verified against Go tolerance limits. Typical applications include setting micrometers, verniers, and other bench measuring devices to a known reference diameter. It is well suited for tool rooms, machine shops, and quality labs performing in-process or final inspection on parts with 0.388-inch nominal bore features. The 2.0-inch overall length provides comfortable handling during routine gage checks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance class for Go inspection applications\u003c\/li\u003e\n  \u003cli\u003e0.388-inch measurement diameter with 0.0002-inch tolerance\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for accurate, repeatable contact\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eCompliant with ASME B89.1 gage standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for Go inspection of 0.388-inch nominal bore diameters.

Clean the gage and the bore thoroughly before use to prevent debris from affecting readings or causing surface damage. Store the gage in its protective case when not in use to preserve the microfinish and dimensional integrity. Do not use excessive force when inserting the gage into a bore, as this can damage both the gage and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.388 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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 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: 111138800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51747574776114,"sku":"111138800","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc5fd382dfcb07726f1e2418ce919e63_79359ae1-7ae3-4852-922c-02807d5d1646.jpg?v=1788882822","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111138800-class-zz-plus-plug-gage-0-388-in","provider":"Voomi Supply","version":"1.0","type":"link"}
