It measures hole diameters of 0.105 inches with a tolerance of 0.0002 inches, making it suitable for verifying close-tolerance bores in machined components. Constructed from steel, this gage provides consistent, repeatable results in shop-floor or lab environments. Machinists, quality technicians, and tool-and-die professionals rely on plug gages like this one to confirm that drilled or reamed holes meet print specifications before parts move to assembly.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is used in manufacturing, tooling, and metrology settings where precise hole acceptance or rejection decisions are required. It is appropriate for both production floor inspection and incoming material verification. The 0.105-inch diameter targets small-bore applications common in precision machined parts, instrument components, and close-tolerance assemblies. A single gage is supplied per package, suitable for individual use or integration into a broader gage set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating for reliable go\/no-go inspection of small-diameter bores\u003c\/li\u003e\n  \u003cli\u003e0.105-inch measurement diameter with 0.0002-inch tolerance for high-precision verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under shop conditions\u003c\/li\u003e\n  \u003cli\u003eCompact single-gage package suitable for bench use or field inspection kits\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy handling during repetitive inspection tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inspection tool for verifying 0.105-inch diameter holes in machined parts and assemblies where Class ZZ Plus gage standards apply.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality technicians following standard metrology practices. Clean the gage and the bore being measured before use to prevent debris from affecting readings. Do not force the gage into a hole, as this can damage both the gage and the workpiece. Store the gage in a protective case away from temperature extremes to maintain dimensional accuracy over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.105 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: 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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 29-105-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720567554354,"sku":"29-105-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c07a0f575be7b0ab8cee443915c61cc.jpg?v=1788566230","url":"https:\/\/voomisupply.com\/products\/spi-29-105-4-class-zz-plus-plug-gage-0-105-in","provider":"Voomi Supply","version":"1.0","type":"link"}
