Built from steel with a black oxide finish, each gage holds a plus-tolerance of 0.0002 inches, meeting NIST Traceable standards. The set is used to verify hole diameters, slot widths, and hole-to-hole spacing with repeatable precision. Machinists, quality-control technicians, and toolroom professionals rely on sets like this for go-gage inspection and for calibrating or setting micrometers, verniers, and other measuring instruments. A Certificate of Accuracy with NIST Traceability is included with every set.\u003c\/p\u003e\u003cp\u003eThis plug gage set is suited for precision inspection work in machine shops, manufacturing floors, and toolrooms handling small-diameter bore verification. Typical applications include measuring hole diameters, gaging slot widths and locations, calculating distances between holes, and setting handheld measuring devices to known reference values. The 190-piece range makes the set practical for shops working across a wide variety of close-tolerance hole sizes in the 0.061 to 0.25 inch range without needing to source individual wire gages separately.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e190-piece set covers 0.061 to 0.25 inches in diameter range\u003c\/li\u003e\n\u003cli\u003eClass ZZ tolerance of plus 0.0002 inches per gage\u003c\/li\u003e\n\u003cli\u003eSteel construction with black oxide finish for corrosion resistance and durability\u003c\/li\u003e\n\u003cli\u003eNIST Traceable Certificate of Accuracy included\u003c\/li\u003e\n\u003cli\u003eSuitable for go-gage inspection, hole diameter measurement, and instrument calibration\u003c\/li\u003e\n\u003cli\u003ePlus-tolerance type conforms to standard Class ZZ gage specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use as a Class ZZ plug gage set in precision inspection and quality-control applications requiring diameter verification in the 0.061 to 0.25 inch range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are handled and used by quality technicians and machinists  -  no power source or mechanical installation is required. Store gages in their designated slots or case to prevent damage to gage surfaces. Clean and lightly oil gage pins before storage to maintain finish and dimensional integrity. Handle with care to avoid dropping, which can alter the gage diameter or damage the black oxide finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 0.061 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (plus)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: ZZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 190\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NIST Traceable\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\u003eWeight\u003c\/strong\u003e: 6 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 901100400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51788233900338,"sku":"901100400","price":270.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11abd8583833b3b5c492b3f19e3911b5.jpg?v=1789225486","url":"https:\/\/voomisupply.com\/products\/vermont-gage-901100400-class-zz-plug-gage-set-190-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
