It measures a nominal diameter of 0.411 inches and is constructed from steel for durability in shop environments. Class ZZ Plus gages are go\/no-go inspection tools used in dimensional quality control. Machinists, tool-and-die technicians, and metrology staff use plug gages to confirm that drilled, reamed, or bored holes fall within print tolerance. The 29-411-6 is a single-end gage suited for repetitive inspection tasks on the shop floor or in a quality lab.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is appropriate for use in precision machining, fabrication, and inspection environments where hole diameter conformance must be verified before assembly. It is well-suited for checking holes in metal components where a 0.411-inch nominal diameter is specified. Class ZZ Plus represents a commercial-grade tolerance class commonly used for production inspection rather than master or reference gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.411-inch nominal measurement diameter for direct bore inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance class rated at 0.0002 inches for production-grade accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance during repetitive use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy one-handed handling\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for individual tooling requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition to existing plug gage sets for production inspection of 0.411-inch nominal diameter holes in machined metal components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages do not require permanent installation. Handle the gage with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, verify the gage is clean and free of debris that could affect measurement accuracy. Store in a protective case away from temperature extremes to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.411 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (mm)\u003c\/strong\u003e: 0.0002 mm\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\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: 29-411-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721260237106,"sku":"29-411-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b398ea79a5c1102eef6b6a41e3f8a69.jpg?v=1788575475","url":"https:\/\/voomisupply.com\/products\/spi-29-411-6-class-zz-plus-plug-gage-0-411-in","provider":"Voomi Supply","version":"1.0","type":"link"}
