It measures a nominal diameter of 0.106 inches with a tolerance of 0.0002 inches, making it suitable for precision inspection work in manufacturing, machining, and quality control environments. The gage is constructed from steel for durability and consistent performance under repeated use. Machinists, quality technicians, and tool-room professionals use plug gages like this to confirm that drilled, reamed, or punched holes fall within acceptable dimensional limits.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in precision inspection applications where small hole diameters must be verified to tight tolerances. Typical install and use scenarios include incoming inspection, in-process gauging on machining lines, and final quality checks on fabricated components. The 0.106-inch diameter is well suited for checking small fastener clearance holes, pin holes, and similar features across a range of metal and engineered material parts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus accuracy grade for general-purpose precision inspection\u003c\/li\u003e\n  \u003cli\u003e0.106-inch nominal measurement diameter\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for reliable go\/no-go verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for hardness and long service life\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece design suited for bench and floor inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ Plus plug gage for general-purpose hole inspection in precision machining and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled and stored carefully to prevent damage to the gauging surface, as nicks or wear will affect accuracy. Before use, clean both the gage and the part being checked to remove chips, oil, or debris that could cause a false reading. Do not force the gage into a hole; apply light, consistent hand pressure only. Periodic calibration against certified reference 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\u003eMeasurement Diameter\u003c\/strong\u003e: 0.106 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Class\u003c\/strong\u003e: Class ZZ Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 29-106-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715854369074,"sku":"29-106-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc7515ab6bb6ef5b2c268f6884ef46c6.jpg?v=1788519068","url":"https:\/\/voomisupply.com\/products\/spi-29-106-2-class-zz-plus-plug-gage-0-106-in","provider":"Voomi Supply","version":"1.0","type":"link"}
