It measures a nominal diameter of 0.993 inches and is manufactured from steel for durability in shop environments. Class ZZ Plus gages meet standard go\/no-go verification requirements and are suited for inspection of production parts where precise dimensional control is required. Machinists, quality technicians, and tool-and-die professionals use plug gages as part of incoming and in-process inspection routines.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is appropriate for use in machine shops, manufacturing facilities, and metrology labs where hole diameter conformance must be confirmed. It is used to check bores and drilled or reamed holes in metal, plastic, or composite workpieces. The 0.993-inch size makes it suitable for medium-range bore inspection tasks common in general machining and precision fabrication work. It is a single-piece gage suited for bench inspection or point-of-operation checking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.993 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for reliable go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece design suited for bench or floor inspection use\u003c\/li\u003e\n  \u003cli\u003eTolerance value also expressed as 0.0002 mm for dual-unit reference\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 verifying 0.993-inch nominal bore diameters in general machining and precision inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, quality control inspectors, and metrology technicians. No power source or fastening is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a bore, as this can damage both the gage and the workpiece and will produce unreliable readings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.993 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\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: 29-993-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720604909874,"sku":"29-993-3","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3257db9a81fbf9945a2a64e04e9bc56.jpg?v=1788566795","url":"https:\/\/voomisupply.com\/products\/spi-29-993-3-class-zz-plus-plug-gage-0-993-in","provider":"Voomi Supply","version":"1.0","type":"link"}
