Manufactured from tool steel with a 10 micro-inch surface finish, this gage checks a 20.69 mm diameter with a tolerance of 0.00508 mm. It ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for documented quality control processes. Machinists, quality technicians, and metrologists use this type of gage for go inspection on production parts and for calibrating or verifying micrometers, verniers, and other measuring devices. The overall length is 2.0 inches, and the unit weighs 0.3 pounds.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in machine shops, tool rooms, and manufacturing inspection departments handling precision components. It is appropriate for both incoming inspection and in-process quality checks where bore diameter must be confirmed to close tolerance. The Class ZZ Plus designation indicates a tighter tolerance grade than standard Class ZZ, making it well suited for applications requiring higher gage accuracy. Compatible with standard gage handle sets for ease of use during repetitive inspection cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20.69 mm inspection diameter with 0.00508 mm tolerance for precision go inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade offers tighter accuracy than standard Class ZZ\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e10 micro-inch surface finish supports consistent, repeatable contact measurement\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for documented QC programs\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 standards for plain plug gages\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection applications and compatible with standard gage handle systems.

Always clean the gage and the bore being inspected before use to prevent false readings or surface damage. Store the gage in its protective case when not in use to prevent corrosion and surface wear. Calibration intervals should follow your facility quality plan and applicable ASME or ISO metrology standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 20.69 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: 0.3 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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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: 112320690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51728849764658,"sku":"112320690","price":20.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_6b588758-af3e-4cc7-bca4-65085b4a8bc4.jpg?v=1788696803","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112320690-class-zz-plus-plug-gage-20-69-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
