It measures a nominal diameter of 0.946 inches, making it suited for go\/no-go inspection work in manufacturing, machining, and quality-control environments. Constructed from steel, this plug gage delivers the dimensional stability required for accurate bore verification. Machinists, quality technicians, and tool-and-die professionals use plug gages like this one to confirm that drilled, reamed, or bored holes fall within specification before assembly or shipment.\u003c\/p\u003e\n\u003cp\u003eClass ZZ Plus plug gages are designed for production-level inspection where repeatability and traceability matter. This gage is appropriate for use on machined components in industrial and manufacturing settings where hole-diameter conformance is a critical quality checkpoint. Its compact form and lightweight build at 0.2 pounds make it easy to handle during high-volume inspection runs on the shop floor or at a quality station.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.946 inches for precise bore inspection\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches meets Class ZZ Plus accuracy requirements\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides dimensional stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy handling during repeated use\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity supports individual tooling procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug gage for production and quality-inspection applications requiring a 0.946-inch nominal bore diameter check at Class ZZ Plus tolerance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are used by machinists and quality-control technicians and require no permanent installation. Ensure the gage and workpiece are clean and free of burrs or debris before use to avoid false readings or gage wear. Store the gage in its protective case when not in use to maintain calibration integrity. Periodic recalibration against a traceable standard is recommended per your facility quality-management procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.946 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (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  \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: 29-946-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696834117938,"sku":"29-946-1","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb931aefed210fe0414a53a57333ce8c.jpg?v=1788346825","url":"https:\/\/voomisupply.com\/products\/spi-29-946-1-class-zz-plus-plug-gage-0-946-in-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
