Designed for go-type inspection of small bores and holes, it checks that a feature falls within its minimum material condition. The gage measures 0.29 mm in diameter and holds a tolerance of 0.00508 mm, making it suitable for high-precision inspection work in metrology labs, machine shops, and manufacturing environments. A 10 microfinish surface treatment reduces wear and ensures repeatable contact. A Certificate of Accuracy with NIST traceability ships with every unit, supporting calibration documentation requirements common in regulated or quality-controlled facilities.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used for go inspection of bore diameters at 0.29 mm, and also serves as a setting standard for micrometers, verniers, and other measuring devices that require a known reference. It is suited for incoming inspection, first-article inspection, and in-process quality checks in precision machining, tool and die, aerospace component manufacturing, and similar applications where small-bore accuracy is critical. Licensed metrologists, quality technicians, and precision machinists are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance grade — 0.00508 mm tolerance for high-precision go inspection\u003c\/li\u003e\n  \u003cli\u003e0.29 mm diameter for small-bore and micro-hole inspection applications\u003c\/li\u003e\n  \u003cli\u003eTool steel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003e10 microfinish surface coating minimizes wear and maintains gage accuracy over time\u003c\/li\u003e\n  \u003cli\u003eIncludes Certificate of Accuracy with NIST traceability for calibration and quality records\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B89.1 standards for dimensional measurement tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for go inspection of 0.29 mm diameter features, and for use as a setting reference with micrometers, verniers, and other precision measuring devices where a certified dimensional standard is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages of this type are handled and deployed by metrology technicians and quality control personnel — not installed in the traditional mechanical sense. Store the gage in its protective case when not in use to prevent surface damage. Before use, clean both the gage and the feature being checked with a lint-free cloth to remove oils and debris that could affect readings. Never force the gage into a bore; light, guided insertion is required to avoid altering the gage surface or the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.29 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\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: 0.01 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: 112300290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERMONT GAGE","offers":[{"title":"Default Title","offer_id":51728225075506,"sku":"112300290","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e13974c1d9df6113e1f89efb9f32744_d9cdbef0-d68d-4d8e-9cf5-16f274a6f7ee.jpg?v=1788689856","url":"https:\/\/voomisupply.com\/products\/vermont-gage-112300290-class-zz-plus-plug-gage-0-29mm","provider":"Voomi Supply","version":"1.0","type":"link"}
