Designed for go-inspection work, this gage checks that a hole meets its minimum acceptable size before a part moves forward in the production or quality process. It carries a tolerance of 0.00508 mm and a 10 microfinish surface finish, giving metrology and QC technicians a reliable, calibration-grade reference. A Certificate of Accuracy with NIST traceability is included, satisfying most shop-floor and ISO audit documentation requirements. The overall length is 2.0 inches, keeping it manageable in tight inspection setups.\u003c\/p\u003e\u003cp\u003eThis plug gage is suited for use in machine shops, manufacturing facilities, and precision assembly environments where bore diameters must be verified against tight tolerances. It is compatible with go-inspection routines and can also be used to set micrometers, verniers, and other measuring devices requiring a known reference diameter. At 4.75 mm, it covers a bore size common in small mechanical assemblies, hydraulic fittings, and precision machined components. Quality control technicians, machinists, and metrologists are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ Plus tolerance rating of 0.00508 mm for high-accuracy go-inspection\u003c\/li\u003e\n\u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n\u003cli\u003e10 microfinish surface finish for consistent, repeatable contact measurement\u003c\/li\u003e\n\u003cli\u003eOverall length of 2.0 inches for practical handling in bench and inline inspection\u003c\/li\u003e\n\u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for audit and calibration records\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B89.1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for go-inspection of 4.75 mm diameter bores and for setting micrometers, verniers, and other measuring devices requiring a calibrated reference standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are handled and used by quality control technicians and machinists; no permanent installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain surface finish integrity. Do not force the gage into a bore — go gages should enter under their own weight or with minimal hand pressure. Store in the provided case and recalibrate on a schedule consistent with ASME B89.1 and your facility quality plan.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.75 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\u003eSurface Finish\u003c\/strong\u003e: 10 Microfinish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\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; Setting Micrometers, Verniers, and Other Measuring Devices\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 112304750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51730931548466,"sku":"112304750","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c0e2e966b45b2513cf9b7c5dd09a18c_ef255014-e9cc-4b03-83b7-bc903c4b60b7.jpg?v=1788724973","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112304750-class-zz-plus-plug-gage-4-75mm","provider":"Voomi Supply","version":"1.0","type":"link"}
