Built from steel, this go-type gage is ground to a minus tolerance of 0.0002 inches, meaning the gage diameter falls at or just below the nominal size. Machinists, quality control inspectors, and precision manufacturers rely on Class ZZ plug gages for production-floor inspection of hole diameters where tight tolerance control is required. The minus configuration ensures the gage enters an acceptable hole without interference when the hole is at or above minimum acceptable size.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in machine shops, manufacturing facilities, and quality inspection environments where bore diameter verification is part of standard process control. It is appropriate for inspecting drilled, reamed, or bored holes in metal, plastic, or composite workpieces. Class ZZ is the standard tolerance class for plug gages used in general production inspection, as defined by ANSI and related dimensional standards. The 0.758-inch diameter range positions this gage for use with medium-to-large bore applications common in industrial and precision machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.758 inches for precise bore inspection at that size\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.0002 inches for reliable go-type dimensional verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability in production environments\u003c\/li\u003e\n  \u003cli\u003eMinus designation ensures gage falls at or below nominal, consistent with go-gage function\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand use during inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Class ZZ minus plug pin gage for general production inspection of machined holes and bores at a nominal diameter of 0.758 inches, compatible with standard gage handle sets designed for that diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are used by quality inspectors and machinists and require no permanent installation. Before use, clean the bore and gage surfaces thoroughly to remove chips, coolant, and debris that could affect measurement accuracy. Store the gage in a protective case away from other tools to prevent surface damage. Handle with care and re-calibrate or replace if the gage shows signs of wear, corrosion, or dimensional drift beyond allowable limits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.758 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\u003eTolerance (Decimal Inch)\u003c\/strong\u003e: 0.0002 inches\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\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: 19-758-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51696808132914,"sku":"19-758-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4757c88fca6224570472b815ab3e28f6.jpg?v=1788346486","url":"https:\/\/voomisupply.com\/products\/spi-19-758-2-class-zz-minus-plug-pin-gage-0-758-in","provider":"Voomi Supply","version":"1.0","type":"link"}
