Built from steel, it delivers a dimensional tolerance of 0.0002 inches, making it suitable for moderate-precision inspection tasks in production and maintenance environments. Machinists, quality technicians, and tool-and-die professionals use plug gages like this one to quickly verify that an internal diameter meets print requirements without relying on variable measurement instruments. At 0.2 pounds, the gage is lightweight and easy to handle during repetitive inspection work.\u003c\/p\u003e\n\u003cp\u003eThe 29-366-2 is suited for shop-floor inspection of internally machined features in light manufacturing, maintenance repair, and general metalworking applications. It is appropriate for use on ferrous and non-ferrous workpieces where a 0.366-inch nominal bore diameter must be confirmed to tolerance. Class ZZ Plus gages are typically applied in situations where production volumes are moderate and inspection frequency is high, providing a fast, reliable check without complex setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.366-inch nominal diameter for direct go\/no-go bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance of 0.0002 inches for reliable moderate-precision verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under regular shop-floor use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for comfortable single-hand operation\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity supports individual replacement or addition to gage sets\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 inspection of internal bores with a 0.366-inch nominal diameter in general machining and manufacturing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled by quality control technicians and machinists and require no installation in the conventional sense, but proper use practice is essential for accurate results. Clean both the gage and the workpiece bore thoroughly before inspection to prevent debris from causing false readings or premature gage wear. Apply gages with light, consistent hand pressure — never force a plug gage into a bore, as this can damage the gage surface and compromise accuracy. Store the gage in a protected case away from other metal tools to prevent nicks or corrosion that would affect the gage diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.366 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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: 29-366-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700640055602,"sku":"29-366-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a3d5db831278a214c477bc05c12f763.jpg?v=1788393158","url":"https:\/\/voomisupply.com\/products\/spi-29-366-2-class-zz-plus-plug-gage-0-366-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
