This gage checks whether a hole or bore meets minimum acceptable diameter requirements during go inspection operations. At 1.43 mm in diameter with a tolerance of 0.005 mm, it delivers the dimensional accuracy required for tight-tolerance inspection work. A 10 microfinish surface treatment on the gage pin reduces wear and ensures repeatable contact with the workpiece. It ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO-registered shops and quality audit trails.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in machine shops, production floors, and quality control labs where small-diameter bore verification is part of routine inspection. It is used alongside set micrometers, verniers, and other measuring devices to confirm hole dimensions before assembly or final inspection. The 2.0-inch overall length provides adequate handling clearance for bench or in-process inspection setups. Typical users include quality technicians, machinists, and metrology professionals working with precision-machined components requiring sub-millimeter hole tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance classification for go inspection of 1.43 mm diameter bores\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability and resistance to wear during repeated use\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface on the gage pin for consistent, accurate contact\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.005 mm meets ASME B89.1 standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for quality documentation\u003c\/li\u003e\n  \u003cli\u003eCompatible with set micrometers, verniers, and general measuring device calibration workflows\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection use with set micrometers, verniers, and other measuring devices where 1.43 mm bore verification is required.

Store the gage in its protective case when not in use to prevent damage to the precision-ground pin surface. Clean the gage pin and bore being measured before use to avoid debris-induced false readings. Do not force the gage into an undersized hole, as this can damage the pin surface and invalidate calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1.43 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.005 mm\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 Microfinish\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\u003eApplication\u003c\/strong\u003e: Go Inspection, Set 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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 112301430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51733055209778,"sku":"112301430","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9ac4452eee4f4eabd4dc2662727a806_325c2ff3-0419-48d7-9873-d10ad84a1f81.jpg?v=1788750989","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112301430-class-zz-plus-plug-gage-1-43mm","provider":"Voomi Supply","version":"1.0","type":"link"}
