It is designed for go-type inspection of bored holes, drilled passages, and machined features where dimensional conformance to ASME B89.1 standards is required. The gage holds a tolerance of 0.005 mm (0.00508 mm actual), making it suitable for precision measurement workflows. Each unit ships with a Certificate of Accuracy that carries full NIST traceability, supporting quality documentation requirements in production and inspection environments. Machinists, quality control technicians, and tool-room professionals are the primary users of this gage.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is applied in go inspection routines to verify that a feature is within its minimum acceptable size limit. Typical applications include checking machined bores on CNC-turned or milled components, calibrating or verifying setting masters for micrometers, verniers, and other variable measuring devices, and supporting first-article and in-process inspection on the shop floor. The 19.42 mm size fits common metric bore applications in both light manufacturing and precision machining operations. The overall length of 2.0000 inches suits standard gage handle systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.005 mm for reliable go-inspection accuracy\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for hardness and wear resistance during repeated use\u003c\/li\u003e\n  \u003cli\u003e10 Micro surface finish coating supports consistent contact with machined bores\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 dimensional gage standards\u003c\/li\u003e\n  \u003cli\u003eCompatible with setting micrometers, verniers, and other measuring devices as a reference master\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for go inspection of 19.42 mm diameter bored or machined features, and for use as a setting reference with micrometers, verniers, and other variable measuring devices per the application data provided.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and applied by quality technicians and machinists following standard metrology practice. Before use, clean the gage and the bore being checked with a lint-free cloth to remove chips, coolant, and debris that would affect the reading. Apply only hand pressure when inserting the gage into a bore — never force a plug gage, as this damages the gage and the workpiece. Store the gage in its protective case away from other tooling to prevent nicks and corrosion on the ground surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 19.42 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.005 mm (0.00508 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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\u003eCoating\/Finish\u003c\/strong\u003e: 10 Micro\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: 0.26 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: 112119420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51754090004786,"sku":"112119420","price":20.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_cbbb4f92-cc4f-4098-9616-ce5eaaed4e8f.jpg?v=1788943339","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112119420-class-zz-plus-plug-gage-19-42mm","provider":"Voomi Supply","version":"1.0","type":"link"}
