It delivers a tolerance of 0.0002 inches, making it suitable for precision inspection work in machining, manufacturing, and quality-control environments. Constructed from steel, the gage maintains dimensional stability under repeated use. Machinists, quality technicians, and tool-and-die professionals use plug gages like this one as a fast, reliable go\/no-go check during in-process or final inspection. The part weighs 0.2 pounds and ships as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is intended for applications where hole diameter conformance must be verified against tight tolerances. Class ZZ Plus gages are commonly used in production inspection of drilled, reamed, or bored holes in metal and other rigid materials. The 29-720-0 is well suited to job-shop and production-floor environments where consistent measurement repeatability is required across multiple operators or shifts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.72 inches for direct bore verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for precision inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for dimensional stability and durability under repeated use\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package for straightforward inventory and toolcrib management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fixed-limit plug gage for use in standard go\/no-go inspection setups on bored or reamed holes with a nominal diameter of 0.72 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and applied by quality technicians or machinists and require no tools for use beyond proper gage-handling procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion and dimensional drift. Do not force the gage into an undersized bore, as this will damage the gage surface and compromise measurement accuracy. Store in a protective case away from temperature extremes to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.72 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: 29-720-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698867831090,"sku":"29-720-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f075ed1df95fddd5b8f81cf5060e8a2.jpg?v=1788369100","url":"https:\/\/voomisupply.com\/products\/spi-29-720-0-class-zz-plus-plug-gage-0-72-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
