It measures 12.83 mm in diameter with a tolerance of 0.00508 mm and a surface finish of 10 microinch, meeting the precision demands of production and quality-control environments. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming dimensional compliance at the time of manufacture. Metrology technicians, machinists, and quality inspectors use this gage to verify that bored, drilled, or reamed holes meet minimum-size acceptance criteria before assembly.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for go inspection of 12.83 mm diameter bores in production machining, tool-and-die, and precision manufacturing settings. It is also used to set and verify micrometers, verniers, and other comparative measuring devices. The Class ZZ Plus tolerance class makes it appropriate for commercial and general-purpose inspection where tighter go\/no-go discrimination is required beyond standard Class ZZ limits. Typical users include QC departments, machine shops, and precision assembly facilities working to ASME B89.1 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12.83 mm diameter with 0.00508 mm tolerance for precise go-type bore acceptance\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for hardness and wear resistance in repetitive inspection use\u003c\/li\u003e\n  \u003cli\u003e10 microinch surface finish for consistent gage-to-bore contact\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B89.1 standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eSuitable for setting micrometers, verniers, and other measuring devices in addition to go inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of 12.83 mm diameter bores and for use with micrometers, verniers, and other measuring devices requiring a traceable reference standard per ASME B89.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages of this type are handled and used by metrology technicians and quality inspectors rather than installed in mechanical systems. Store the gage in its protective case when not in use to prevent corrosion and surface damage. Clean bore and gage surfaces before inspection to avoid false readings. Calibration intervals should follow the facility quality management plan and applicable ASME B89.1 guidance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12.83 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.00508 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 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\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\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: 112312830\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51732769538354,"sku":"112312830","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_04eea982-d481-43d5-a76e-587353d1cf5c.jpg?v=1788746564","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112312830-class-zz-plus-plug-gage-12-83mm","provider":"Voomi Supply","version":"1.0","type":"link"}
