Built from tool steel with a 10 micro finish, it holds a tolerance of 0.00508 mm, meeting ASME B89.1 standards. Each unit ships with a Certificate of Accuracy traceable to NIST. Machinists, quality technicians, and metrology professionals use this gage to verify that a bore meets minimum acceptable size before a part advances in production or ships to the customer.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for go inspection tasks in manufacturing, machining, and quality control environments. It works alongside micrometers, verniers, bore gages, and other measuring devices to establish a reference or confirm dimensional conformance. With an overall length of 2.0000 inches, it fits standard handle sets and is practical for both bench inspection and in-process checks on the shop floor. It is a single-diameter gage intended for one specific nominal size — 18.55 mm.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance classification — 0.00508 mm tolerance per ASME B89.1\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e10 micro surface finish for consistent, repeatable contact\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable Certificate of Accuracy included with each unit\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.0000 inches — compatible with standard plug gage handles\u003c\/li\u003e\n  \u003cli\u003eGo inspection configuration for verifying minimum bore acceptance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as a go plug gage in applications requiring bore inspection, and for use with micrometers, verniers, and other precision measuring devices per manufacturer specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists — not installed in a system. Clean the gage and bore thoroughly before use to prevent false readings caused by chips or coolant residue. Never force the gage into a bore; go gages should enter under their own weight or with light hand pressure only. Store the gage in its case away from heat sources and magnetic fields to preserve dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 18.55 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\u003eWeight\u003c\/strong\u003e: 0.24 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\u003eClass\u003c\/strong\u003e: ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Go Inspection; 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: 112318550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51737031541042,"sku":"112318550","price":17.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_38d162f5-3de7-4efd-833b-1a68afd08d82.jpg?v=1788783403","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112318550-class-zz-plus-plug-gage-18-55mm","provider":"Voomi Supply","version":"1.0","type":"link"}
