It carries a tolerance of 0.00508 mm, meeting ASME B89.1 accuracy standards for go inspection work. The gage ships with a Certificate of Accuracy traceable to NIST, making it suitable for calibrated measurement environments. Overall length is 2.0000 inches. Machinists, quality technicians, and metrology professionals use this gage to verify hole diameter acceptance before assembly or final inspection sign-off.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in production and inspection settings where hole diameter conformance must be confirmed using a physical go gage method. Typical applications include verifying bored, reamed, or drilled holes in metal components during in-process or final inspection. It is also used to set and verify the calibration of micrometers, verniers, and other comparative measuring devices. The 10 micro surface finish on the gage pin supports accurate, repeatable contact with the workpiece bore surface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance class at 0.00508 mm for precision go inspection\u003c\/li\u003e\n  \u003cli\u003eNominal diameter of 21.41 mm for direct hole size verification\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for hardness and wear resistance in production use\u003c\/li\u003e\n  \u003cli\u003e10 micro surface finish on gage pin for consistent bore contact\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B89.1 dimensional gage standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for calibrated environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of 21.41 mm diameter bored, reamed, or drilled holes, and for setting micrometers, verniers, and other comparative measuring instruments requiring a reference standard of this diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by quality technicians and machinists following standard metrology practices. Store the gage in its protective case when not in use and keep it clean and lightly oiled to prevent corrosion on the tool steel surfaces. Never force the gage into an undersized bore, as this will damage both the gage pin and the workpiece. Periodic recalibration against NIST-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: 21.41 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: 0.32 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\u003eTolerance Class\u003c\/strong\u003e: Class ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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\u003eApplication\u003c\/strong\u003e: Go Inspection, Setting Micrometers, Verniers, and Other Measuring Devices\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: 112321410\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51734960832818,"sku":"112321410","price":22.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf04934d75d3eb37d973f6ea4b25c4d_6d9c2e58-54f0-406a-acd8-c2e95f500014.jpg?v=1788768584","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112321410-class-zz-plus-plug-gage-21-41mm","provider":"Voomi Supply","version":"1.0","type":"link"}
