Machined from tool steel with a 10 microinch surface finish, it measures a nominal diameter of 0.77 inches and holds a tolerance of 0.0002 inches. The gage ships with a Certificate of Accuracy traceable to NIST, confirming compliance with ASME B89.1 standards. Quality control technicians and precision machinists use this tool to verify that bored, drilled, or reamed holes fall within specified limits before parts move to the next stage of production or assembly.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for go inspection applications in manufacturing, toolroom, and quality assurance environments. It is also used as a reference standard for setting micrometers, verniers, and other measuring devices that require a known diameter for calibration or zero-setting. The 2.0-inch overall length provides a comfortable handle for single-hand operation at the inspection bench or on the shop floor. Both production shops and metrology labs rely on Class ZZ Plus gages for reliable, repeatable diameter verification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.77 inches for precise hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for consistent go-inspection performance\u003c\/li\u003e\n  \u003cli\u003e10 microinch surface finish for accurate, repeatable contact with bore surfaces\u003c\/li\u003e\n  \u003cli\u003eTool steel construction provides durability and wear resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability, meeting ASME B89.1 requirements\u003c\/li\u003e\n  \u003cli\u003eSuitable for setting micrometers, verniers, and other precision measuring devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Class ZZ Plus plug gage for go inspection of 0.77-inch nominal diameter holes and bores, and for use as a reference standard with micrometers, verniers, and comparable precision measuring instruments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality control technicians and toolroom personnel. Store the gage in its protective case when not in use and apply a light coat of rust-preventive oil to prevent corrosion from handling. Do not force the gage into an undersized hole, as this can damage the gage surface and invalidate its calibration. Verify the gage certificate is current and that the instrument has not been subjected to impact or excessive wear before use in a critical inspection sequence.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.77 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\u003eApplication\u003c\/strong\u003e: Go Inspection; Setting Micrometers, Verniers, and Other Measuring Devices\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\u003eStandard\u003c\/strong\u003e: ASME B89.1\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: 111177000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51744770752818,"sku":"111177000","price":20.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_a10b9a80-a8fc-49da-b70f-4697d5299e59.jpg?v=1788860323","url":"https:\/\/voomisupply.com\/products\/vermont-gage-111177000-class-zz-plus-plug-gage-0-77-in","provider":"Voomi Supply","version":"1.0","type":"link"}
