Built to a nominal diameter of 0.73 inches with a tolerance of 0.0002 inches, this gage provides reliable go\/no-go verification for tight-tolerance work. The steel construction delivers the hardness and wear resistance needed for repeated use on production floors and in quality control settings. Licensed machinists, metrology technicians, and quality inspectors are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for verifying hole sizes in machined components across light manufacturing, toolroom work, and incoming inspection. It fits into standard gage handle assemblies and is used wherever consistent, repeatable bore verification is required. The Class ZZ Plus designation indicates this gage meets ANSI tolerance standards for workshop-grade inspection tools, making it appropriate for production-level checks rather than master or reference-grade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.73 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches meets Class ZZ Plus ANSI standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides hardness and long service life under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy single-hand operation\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard plug gage handle assemblies\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 workshop and production inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are installed and used by machinists and quality control technicians. Before use, clean the gage and the bore being measured to remove chips, coolant, and debris that could affect readings. Handle the gage carefully to avoid dropping or striking, as impact damage can alter the calibrated diameter. Store in a protective case away from moisture to prevent corrosion of the steel construction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Diameter\u003c\/strong\u003e: 0.73 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\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\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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: 29-730-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721314795826,"sku":"29-730-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe328ed47f5e134d4b88eee0f6052e0a.jpg?v=1788576313","url":"https:\/\/voomisupply.com\/products\/spi-29-730-9-class-zz-plus-plug-gage-0-73-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
