Built to a tolerance of 0.0002 inches, this gage checks whether a bored, drilled, or reamed hole falls within the specified acceptance range. The 0.41-inch diameter measurement range suits a wide variety of machined component inspection tasks. Constructed from steel for durability and dimensional stability, it is a standard tool in quality control operations across machining, fabrication, and manufacturing facilities.\u003c\/p\u003e\u003cp\u003eClass ZZ Plus plug gages are used in dimensional inspection workflows where quick, reliable verification of hole size is required. They are commonly employed on the shop floor or in inspection rooms for checking production parts against engineering tolerances. This gage is appropriate for moderate-precision applications where a hardened, accurate go\/no-go check is needed without the cost of higher-class gages. Machinists, QC inspectors, and tooling professionals rely on this type of gage during both in-process and final inspection stages.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ Plus tolerance grade for reliable go\/no-go hole inspection\u003c\/li\u003e\n\u003cli\u003e0.41-inch nominal measurement diameter\u003c\/li\u003e\n\u003cli\u003e0.0002-inch tolerance for consistent dimensional verification\u003c\/li\u003e\n\u003cli\u003eSteel construction for wear resistance and long service life\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.2 pounds for easy handheld use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug gage for inspection of 0.41-inch nominal diameter holes in machined components across general manufacturing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages require no permanent installation and should be handled with clean, dry hands or lint-free gloves to prevent corrosion and measurement error. Store the gage in a protective case away from temperature extremes to maintain dimensional accuracy. Calibration intervals should follow your facility's quality management procedures and applicable metrology standards. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.41 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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 29-410-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694109294898,"sku":"29-410-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1f42afa61ec9c07f8795445946a9088.jpg?v=1788320362","url":"https:\/\/voomisupply.com\/products\/spi-29-410-8-class-zz-plus-plug-gage-0-41-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
