It measures 18.63 mm in diameter with a tolerance of 0.00508 mm, making it suitable for Go inspection applications where tight dimensional control is required. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy that includes NIST traceability, supporting quality-system documentation requirements in precision manufacturing and metrology environments. Machinists, quality technicians, and calibration professionals use this gage type as a reliable go\/no-go reference tool.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in production and inspection settings to verify that machined holes fall within acceptable dimensional limits. It is appropriate for use alongside micrometers, verniers, and other measuring devices as a calibration or reference standard. The 18.63 mm diameter makes it a practical choice for mid-range bore inspection in both job shop and production-floor environments. It is manufactured to ASME B89.1 standards, which govern the performance and dimensional requirements of plain plug gages used in general metrology applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade with 0.00508 mm tolerance for precise Go inspection\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability and dimensional stability in shop environments\u003c\/li\u003e\n  \u003cli\u003e10 Micro coating and finish for surface quality consistent with Class ZZ Plus requirements\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for quality-system compliance\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B89.1 standards for plain plug gage performance\u003c\/li\u003e\n  \u003cli\u003eCompatible for use with micrometers, verniers, and other measuring devices as a reference standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for Go inspection applications and for use with micrometers, verniers, and other measuring devices requiring an 18.63 mm diameter reference standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and stored by quality technicians and calibration professionals following standard metrology practices. 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; excessive insertion force can damage both the gage and the workpiece. Store in the provided case or a protected environment to preserve dimensional integrity between uses.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 18.63 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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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\u003eStandards\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: 0.24 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: 112318630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51753849389362,"sku":"112318630","price":17.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_abfd5be5-fd29-4e50-9503-b0795ac360ae.jpg?v=1788941460","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112318630-class-zz-plus-plug-gage-18-63mm","provider":"Voomi Supply","version":"1.0","type":"link"}
