It measures a nominal diameter of 0.648 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy dimensional verification in production and quality control environments. The gage features a 10 microinch surface finish to support consistent, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage to verify bore size acceptability on machined components.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is intended for go inspection of bored, drilled, or reamed holes where a 0.648-inch nominal diameter must be confirmed to tight tolerance. It is also suited for use in calibrating or setting instruments such as micrometers, verniers, and other measuring devices. The 2.0-inch overall length provides a manageable handle grip for bench-top and floor-level inspection tasks. Typical applications include job-shop machining operations, incoming inspection stations, and tool-and-die calibration setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade: 0.0002 inches, suitable for precision go inspection\u003c\/li\u003e\n  \u003cli\u003e10 microinch surface finish for repeatable, accurate contact\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 dimensional gage standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eUseful for setting micrometers, verniers, and other measuring devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of workpiece bores at 0.648 inches nominal diameter and for use as a setting standard with micrometers, verniers, and other handheld measuring devices.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis gage is handled by quality technicians and metrology personnel; no power-down or lockout procedure is required for typical bench use. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion and maintain surface finish integrity. Do not force the gage into an undersized bore, as this can damage the gage surface and affect accuracy. Store in a protective case away from temperature extremes to preserve dimensional stability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.648 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 microinch\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: 111164800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51747405267250,"sku":"111164800","price":16.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_cd53339f-1c62-42f5-a052-85f8e42b4ae0.jpg?v=1788879578","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111164800-class-zz-plus-plug-gage-0-648-in","provider":"Voomi Supply","version":"1.0","type":"link"}
