The gage measures 0.755 inches in diameter and is manufactured from steel, providing the durability needed for repeated use in shop-floor and quality-control environments. With a tolerance of 0.0002 inches, it conforms to Class ZZ specifications, making it appropriate for general-purpose go\/no-go inspection applications. Machinists, quality technicians, and tool-and-die professionals use plug gages like this to confirm that drilled, reamed, or bored holes fall within acceptable dimensional limits before parts move to assembly.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in production inspection, incoming material verification, and first-article inspection across metalworking, fabrication, and precision manufacturing environments. Class ZZ plug gages are commonly applied where standard commercial tolerances are acceptable rather than the tighter limits required by Class Z or ZZ-plus gages. The 0.755-inch diameter makes it useful for checking holes in medium-range bore applications typical in general machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance class for general-purpose hole inspection\u003c\/li\u003e\n  \u003cli\u003e0.755 inch nominal diameter for medium-range bore verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for reliable go\/no-go gauging\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package suitable for individual workstation use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose plug pin gage for use in standard go\/no-go inspection setups where a 0.755 inch diameter Class ZZ minus gage is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Before use, inspect the gage surface for nicks or wear that could affect measurement accuracy. Store the gage in its protective case when not in use and apply a light coat of rust-preventive oil for long-term storage. Calibration intervals should follow your facility quality management procedures and applicable metrology standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.755 inches\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\u003eTolerance (mm)\u003c\/strong\u003e: 0.0002 mm\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: 19-755-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51701002961202,"sku":"19-755-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d34b68dded24111c51c20052462ed09d.jpg?v=1788396590","url":"https:\/\/voomisupply.com\/products\/spi-19-755-8-class-zz-minus-plug-pin-gage-0-755-in","provider":"Voomi Supply","version":"1.0","type":"link"}
