Manufactured from tool steel with a 10 micro finish, this gage provides a tolerance of 0.005 mm (0.00508 mm actual), meeting the dimensional accuracy requirements of ASME B89.1. It ships with a Certificate of Accuracy traceable to NIST, supporting documented quality-control workflows. Machinists, quality technicians, and metrologists use this gage to verify that a hole is within its lower acceptance boundary before a part advances in production or assembly.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for incoming inspection, in-process quality checks, and final acceptance testing in machine shops, toolrooms, and manufacturing environments. It is used with go inspection protocols to confirm bore size compliance on machined components. The gage is also appropriate for calibrating and verifying set micrometers, verniers, and other measuring devices requiring a traceable reference standard. Its 2.0000-inch overall length fits standard gage handle designs used in typical bench inspection setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade per ASME B89.1 for go inspection applications\u003c\/li\u003e\n  \u003cli\u003e17.94 mm nominal diameter with 0.005 mm tolerance\u003c\/li\u003e\n  \u003cli\u003eTool steel construction with 10 micro surface finish for repeatable contact measurement\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for calibration documentation\u003c\/li\u003e\n  \u003cli\u003e2.0000-inch overall length compatible with standard plug gage handles\u003c\/li\u003e\n  \u003cli\u003eSuitable for setting and verifying micrometers, verniers, and other measuring instruments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in go inspection of bores at 17.94 mm nominal diameter.

Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; go gages should enter under their own weight or with light hand pressure only. Store in the provided case or a dedicated gage block to prevent contact damage that would affect accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 17.94 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\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\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\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\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: 112117940\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51748720148786,"sku":"112117940","price":17.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_af66a933-ff43-404f-b6ab-bec582c83246.jpg?v=1788897246","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112117940-class-zz-plus-plug-gage-17-94mm","provider":"Voomi Supply","version":"1.0","type":"link"}
