Built from steel, it delivers the dimensional stability required for accurate go\/no-go inspection work on the shop floor or in a quality control setting. The minus tolerance classification means the gage is manufactured slightly below nominal, a standard approach for checking minimum material condition. With a tolerance of 0.0002 inches, this gage meets Class ZZ specifications for general-purpose inspection tasks. Machinists, quality technicians, and tool-and-die professionals use plug pin gages as a fast, reliable method to confirm whether a hole is within acceptable limits without requiring a measuring instrument readout.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in manufacturing, machining, and fabrication environments where hole diameter verification is part of routine inspection. It is appropriate for checking drilled, reamed, or bored holes in metal, plastic, or composite workpieces. At 0.746 inches, it falls within the mid-range of standard pin gage sets and is commonly used in both low-volume job shops and higher-volume production inspection lines. A single gage is supplied per package, making it a practical replacement or addition to an existing pin gage assortment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance classification for general-purpose bore inspection\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for repeatable dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.746-inch nominal diameter targets a common mid-range bore size\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling during inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ plug pin gage for use with standard pin gage handles and accessories compatible with 0.746-inch diameter gages.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are used by quality control technicians and machinists and require no installation in the traditional sense. Clean the gage and the bore being checked before use to prevent debris from affecting measurement accuracy. Store the gage in a protective case away from temperature extremes to maintain dimensional integrity. Handle with care to avoid dropping or striking the gage, as impact damage can alter the ground diameter and render it out of tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.746 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 Class\u003c\/strong\u003e: Class ZZ Minus\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\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: 19-746-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694025867570,"sku":"19-746-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/523b3a2ebe4ce296776e3b6e1ee5f68f.jpg?v=1788319608","url":"https:\/\/voomisupply.com\/products\/spi-19-746-7-class-zz-minus-plug-pin-gage-0-746-in","provider":"Voomi Supply","version":"1.0","type":"link"}
