Built to a diameter of 0.904 inches with a tolerance of 0.0002 inches, this gage provides reliable go\/no-go measurement confirmation for machined components. The steel construction delivers the durability needed for repeated use on the shop floor or in a quality control lab. Machinists, tool room technicians, and quality assurance inspectors use plug gages like this one to confirm that finished holes meet specification before parts move to assembly.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for dimensional inspection tasks in manufacturing, job shop, and quality lab settings. It is commonly used when verifying drilled, reamed, or bored holes in metal or plastic workpieces that require tight-tolerance confirmation. The 0.904-inch diameter targets a specific bore size that must be verified consistently across production runs. A single-unit package quantity makes this a practical choice for individual inspection stations or as a replacement for a worn gage in an existing set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.904-inch measurement diameter for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating at 0.0002 inches for production-grade inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for direct replacement or individual station use\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 use in any inspection or quality control application requiring 0.904-inch bore diameter verification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, quality technicians, and tool room personnel — no installation in the traditional sense is required. Store the gage in a protective case away from contaminants and temperature extremes to preserve calibration. Clean the gage and the bore surface before use to prevent false readings caused by chips or debris. Periodically inspect the gage for wear and recalibrate or replace it according to your facility measurement system assurance program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.904 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\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 29-904-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698426544434,"sku":"29-904-0","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74a61369274915f8b1b9ec94639f3b1a.jpg?v=1788362672","url":"https:\/\/voomisupply.com\/products\/spi-29-904-0-class-zz-plus-plug-gage-0-904-in","provider":"Voomi Supply","version":"1.0","type":"link"}
