Built from tool steel with a 10 microfinish surface coating, it delivers the dimensional accuracy and surface quality required for precise bore inspection in manufacturing and metrology environments. The gage holds a tolerance of 0.00508 mm, making it suitable for applications where tight process control is essential. It ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements. Licensed metrologists, machinists, and quality technicians are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used to verify that bored, drilled, or reamed holes meet minimum acceptable diameter specifications in a go inspection workflow. It is also used to set and verify micrometers, verniers, and other internal measuring devices. Typical applications include incoming inspection, in-process quality checks, and calibration setups across metalworking, aerospace, automotive, and general manufacturing environments. Each unit ships individually packaged with its NIST-traceable accuracy certificate included.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance classification for go inspection of 12.9 mm internal diameters\u003c\/li\u003e\n  \u003cli\u003e0.00508 mm tolerance for high-precision bore verification\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface coating reduces wear and ensures accurate gauge contact\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability in production inspection environments\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for quality documentation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in go inspection applications and for setting micrometers, verniers, and other internal measuring devices requiring a 12.9 mm reference standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHandle plug gages with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Periodic recalibration against a certified reference standard is recommended per your facility quality plan and applicable metrology standards. Do not force the gage into a bore; light, consistent hand pressure is the correct technique for go inspection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12.9 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.00508 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: 10 Microfinish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\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  \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: 112112900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51754170417458,"sku":"112112900","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_635828cc-cd6e-4ec5-bcc3-59d77fba9360.jpg?v=1788943732","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112112900-class-zz-plus-plug-gage-12-9mm","provider":"Voomi Supply","version":"1.0","type":"link"}
