Manufactured from tool steel with a 10 microfinish surface coating, this gage checks whether a hole falls within acceptable size limits using the Go method. The nominal diameter is 4.90 mm with a tolerance of 0.005 mm, making it suited for precision quality control applications. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in regulated manufacturing and inspection environments. Machinists, toolroom technicians, and quality control inspectors are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in production and inspection settings where bore diameter verification is required on machined components. Typical applications include Go inspection of drilled, reamed, or bored holes in metal or plastic parts. It is also suitable for setting and verifying micrometers, verniers, and other measuring devices. The 4.90 mm size fits common small-bore inspection tasks in precision machining, tooling, and assembly operations across both job-shop and production-line environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade for Go inspection of 4.90 mm diameter bores\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface coating for accurate, repeatable contact\u003c\/li\u003e\n  \u003cli\u003eComplies with ASME B89.1 dimensional gage standards\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for quality records\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 2.0 inches for easy handling in confined inspection setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for Go inspection of 4.90 mm diameter bores and for setting micrometers, verniers, and other measuring devices per ASME B89.1 requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality control technicians  -  no power tools or utilities need to be shut down before use. Store the gage in its protective case when not in use and keep it free of chips, coolant, and debris that can affect accuracy. Do not force the gage into a bore; apply only light hand pressure to avoid damaging the gage or the workpiece. Periodic cleaning and recalibration against NIST-traceable standards is recommended to maintain measurement integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.90 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.005 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\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\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: 112104900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51740787278130,"sku":"112104900","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7e2a647b3184ead6e2e73d5519ba705_cc8507ac-ee1a-4c4b-a6de-40820a45e516.jpg?v=1788827430","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112104900-class-zz-plus-plug-gage-4-9-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
