Manufactured from tool steel with a 10 micro-inch surface finish, this gage delivers a tolerance of 0.00508 mm, meeting ASME B89.1 standards for dimensional gaging. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented quality-control programs. Metrology technicians, tool-and-die shops, and precision machining operations use this gage to verify that bored features fall within acceptable limits before parts advance to the next production stage.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in applications requiring go-type inspection of round bores in both production and receiving inspection environments. It is suited for use alongside set micrometers, verniers, and other calibrated measuring devices. The 2.0-inch overall length provides a comfortable, stable grip for manual gage application. Facilities operating under ISO quality systems or similar quality frameworks will find the included NIST-traceable certificate directly supports calibration records and traceability requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.00508 mm for precise go inspection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 dimensional gaging standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability\u003c\/li\u003e\n  \u003cli\u003eTool steel construction with 10 micro-inch surface finish for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003e2.0-inch overall length for stable manual handling\u003c\/li\u003e\n  \u003cli\u003eCompatible with set micrometers, verniers, and other measuring devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of machined bores and holes at a nominal diameter of 21.85 mm.

Clean the gage and the bore thoroughly before use to prevent debris from affecting the measurement or damaging the gage surface. Store the gage in its protective case when not in use to prevent corrosion and surface wear. Periodic recalibration against traceable standards is recommended to maintain measurement integrity over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 21.85 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: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 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-Inch\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\u003eStandards\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: 112321850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51747472769330,"sku":"112321850","price":22.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_fb54d531-c71d-4008-918b-104f28c1ac20.jpg?v=1788880868","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112321850-class-zz-plus-plug-gage-21-85mm","provider":"Voomi Supply","version":"1.0","type":"link"}
