It measures nominal bore diameters of 0.718 inches with a tolerance of 0.0002 inches, making it suitable for go\/no-go inspection work where tight dimensional control is required. Constructed from steel for durability and wear resistance, this gage is a standard tool in quality control and machining environments. Machinists, toolmakers, and quality inspectors use plug gages like this to verify that drilled, reamed, or bored holes fall within specified tolerance ranges before parts proceed to assembly.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in machine shops, manufacturing facilities, and inspection departments where internal diameter verification is part of routine quality assurance. It is appropriate for both production-line inspection and bench-level metrology tasks. The Class ZZ Plus designation indicates a commercial-grade tolerance class commonly used for inspection of general-tolerance machined workpieces rather than master or reference gage applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.718 inch nominal measurement diameter for precise bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for accurate go\/no-go dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and resistance to wear during repeated use\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus designation suits general-purpose production inspection applications\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy bench and floor use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard plug gage for inspecting internal diameters of 0.718 inches in machined components across general manufacturing and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled and stored carefully to prevent surface damage that could affect measurement accuracy. Before use, clean both the gage and the bore being inspected to remove chips, oils, or debris. Apply light gage oil when appropriate to reduce wear during repeated insertions. Gage calibration should be verified periodically against traceable standards in accordance with your facility quality management program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.718 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\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: 29-718-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51702738747698,"sku":"29-718-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e084847f31546cf7d57447321858818.jpg?v=1788413050","url":"https:\/\/voomisupply.com\/products\/spi-29-718-4-class-zz-plus-plug-gage-0-718-in-diameter","provider":"Voomi Supply","version":"1.0","type":"link"}
