The gage measures a nominal diameter of 0.3945 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy go-inspection applications. Manufactured from tool steel, it features a 10 microfinish surface that supports consistent, repeatable contact with workpiece surfaces. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming it meets ASME B89.1 standards. Machinists, quality technicians, and tool room personnel use this gage in production and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in go inspection applications to verify that bored or reamed holes fall within the specified tolerance for minimum material condition. It is also suitable for setting micrometers, verniers, and other comparative measuring devices to a known reference diameter. Typical applications include machining shops, toolrooms, and quality control stations working with close-tolerance parts in both job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade for go inspection of machined holes and bores\u003c\/li\u003e\n  \u003cli\u003e0.3945 inch nominal diameter with 0.0002 inch tolerance\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface for accurate and repeatable contact\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST Traceability\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a go inspection plug gage for use with machined bores and holes at 0.3945 inch nominal diameter.

Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surfaces. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.3945 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\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: 10 Microfinish\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\u003eApplication\u003c\/strong\u003e: Go Inspection; Setting Micrometers, Verniers, and Other Measuring Devices\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: 111339450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51727138685234,"sku":"111339450","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc5fd382dfcb07726f1e2418ce919e63_0685213a-fc88-4c20-b1be-944e74cc895d.jpg?v=1788673917","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111339450-class-zz-plus-plug-gage-0-3945-in","provider":"Voomi Supply","version":"1.0","type":"link"}
