Manufactured from steel, this go\/no-go style gage checks a nominal diameter of 0.97 inches with a tolerance of 0.0002 inches, providing the accuracy required for close-tolerance production work. Class ZZ Plus gages are designed for use in inspection departments, machine shops, and manufacturing environments where consistent dimensional verification is required. The 29-970-1 weighs 0.2 pounds, making it easy to handle during routine checks.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for inspecting machined holes, bored features, and drilled openings in steel, aluminum, and other workpiece materials where hole size conformance must be confirmed. It is appropriate for use in manufacturing, tool rooms, and quality control environments. The gage is typically used by machinists, quality inspectors, and toolmakers performing in-process or final inspection tasks requiring traceable dimensional measurement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating for precision hole diameter verification\u003c\/li\u003e\n  \u003cli\u003e0.97 inch nominal diameter with 0.0002 inch tolerance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop and inspection environments\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use\u003c\/li\u003e\n  \u003cli\u003eIndividual unit packaging suitable for single-gage inventory management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Class ZZ Plus plug gage for verifying machined holes and bored features at 0.97 inches nominal diameter in standard industrial inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled by qualified machinists or quality inspectors following shop calibration and gage-handling procedures. Clean the gage and the workpiece bore before use to prevent debris from affecting measurement accuracy. Store in a protective case away from temperature extremes to maintain dimensional stability. Do not force the gage into an undersized bore, as this can damage the gage surface and compromise calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance (mm)\u003c\/strong\u003e: 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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 29-970-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51719298744626,"sku":"29-970-1","price":16.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f8a450b13cf07124174d150017696c8.jpg?v=1788558694","url":"https:\/\/voomisupply.com\/products\/spi-29-970-1-class-zz-plus-plug-gage-0-97-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
