Built from steel, this gage holds a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work where dimensional accuracy is critical. Machinists, quality control technicians, and tool-and-die professionals use plug gages like this one to confirm that drilled, reamed, or bored features fall within specification before parts advance to the next stage of production or assembly.\u003c\/p\u003e\n\u003cp\u003eClass ZZ Plus plug gages are typically used in production inspection environments where moderate-precision hole verification is required. This gage is well-suited for checking holes in machined metal components across general manufacturing, job shop, and maintenance applications. Its compact size and straightforward operation make it a standard tool in any metrology or QC setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.301 inches for precise hole verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance classification for production-grade inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eTight tolerance of 0.0002 inches ensures accurate go\/no-go gauging\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy bench or field use\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 standard plug gage handle sets used in production and inspection environments for verifying 0.301-inch nominal bore diameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists or quality control technicians  -  no power shutoff is required. Clean the gage and the bore thoroughly before use to prevent debris from affecting the measurement reading. Store the gage in its case when not in use to protect the precision ground surface from damage or corrosion. Follow your facility's calibration schedule and handle with care to preserve gage accuracy over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.301 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\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: 29-301-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":67917668974898,"sku":"29-301-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/915a12ae46e2c1a570481fe66b7073fc.jpg?v=1791264562","url":"https:\/\/voomisupply.com\/products\/spi-29-301-9-class-zz-plus-plug-gage-0-301-in","provider":"Voomi Supply","version":"1.0","type":"link"}
