It measures a nominal diameter of 0.502 inches and holds a tolerance of 0.0002 inches, meeting the exacting demands of ASME B89.1 standards. The working surface carries a 10 microinch finish, ensuring consistent, repeatable contact with the bore being checked. Each unit ships with a Certificate of Accuracy traceable to NIST. This gage is used by machinists, quality control technicians, and metrology professionals who need a reliable, traceable reference for verifying hole and bore dimensions in production or inspection settings.\u003c\/p\u003e\n\u003cp\u003eThe 111150200 is suited for go inspection of bores, holes, and features at the 0.502-inch nominal size. It is a practical tool for calibrating and verifying set micrometers, verniers, and other measuring devices that require a known, certified reference diameter. The overall length of 2.0 inches makes it compatible with standard gage handle setups. Applications span general machining, quality assurance labs, tool rooms, and any production environment where hole-size conformance must be documented and verified against a traceable standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade — 0.0002 inch tolerance for high-accuracy go inspection\u003c\/li\u003e\n  \u003cli\u003e10 microinch surface finish for consistent, repeatable gage contact\u003c\/li\u003e\n  \u003cli\u003eConstructed from tool steel for durability and wear resistance in production use\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for documented quality compliance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 standards for dimensional gaging\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.0 inches fits standard plug gage handles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard plug gage handles and suitable as a reference for setting micrometers, verniers, and other measuring devices requiring a certified 0.502-inch diameter reference.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists — no power source or mechanical installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Allow the gage and workpiece to stabilize at the same ambient temperature before use, as thermal expansion can affect readings at tight tolerances. Store in the original protective case or a dedicated gage block storage solution to avoid surface damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.502 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 microinch\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\u003eStandards\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, Set 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: 111150200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51734768124210,"sku":"111150200","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_6f0349a2-86e0-45b0-a205-df3283492ed6.jpg?v=1788766815","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111150200-class-zz-plus-plug-gage-0-502-in","provider":"Voomi Supply","version":"1.0","type":"link"}
