It measures hole diameters at 0.613 inches with a tolerance of 0.0002 inches, providing the precision required for go\/no-go inspection work in manufacturing, machining, and quality control environments. The gage body is constructed of steel for durability under repeated use. Machinists, toolmakers, and quality technicians use this type of gage to confirm that hole dimensions meet drawing specifications before parts move to the next stage of production.\u003c\/p\u003e\n\u003cp\u003eThis plug gage is suited for use in job shop and production machining environments where hole tolerances must be verified quickly and reliably. It is appropriate for inspecting holes in metal components across general metalworking, automotive, aerospace, and industrial fabrication applications. The compact form factor allows use at the machine or at a dedicated inspection station. The 0.613-inch nominal diameter makes it a direct fit for inspection of holes produced to that specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ Plus tolerance rating for reliable go\/no-go hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.613-inch nominal measurement diameter\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for precise dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package ready for immediate use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use Class ZZ Plus plug gage for inspecting holes with a nominal diameter of 0.613 inches in standard go\/no-go gage applications across general machining and quality inspection workflows.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled by machinists and quality inspection personnel. Before use, clean the gage and the hole being inspected to remove chips, oil, and debris that could affect the reading. Do not force the gage into a hole; excessive force will damage the gage and produce inaccurate results. Store the gage properly when not in use to prevent corrosion and protect the precision ground surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.613 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\u003eClass\u003c\/strong\u003e: ZZ Plus\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: 29-613-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51711431278898,"sku":"29-613-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d476923aa460b892d2fbed5b98e2699.jpg?v=1788476591","url":"https:\/\/voomisupply.com\/products\/spi-29-613-7-class-zz-plus-plug-gage-0-613-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
