It measures 0.79 inches in diameter and holds a tolerance of 0.0002 inches, making it a reliable tool for go\/no-go gauging applications in production and quality control environments. Constructed from steel for durability and dimensional stability, this gage is used to verify that a hole falls within an acceptable size range. Machinists, tool and die technicians, and quality inspection personnel are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are commonly used in general-purpose inspection where tight tolerances must be confirmed quickly and accurately. The minus designation indicates the gage is manufactured to the lower end of the tolerance range, which is standard practice for plug gages used to check minimum hole size acceptance. This gage is suited for shop floor inspection, incoming material verification, and process control checks across machining, manufacturing, and fabrication operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance classification for general-purpose hole inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation for lower-tolerance-range dimensional verification\u003c\/li\u003e\n  \u003cli\u003e0.79 inch nominal diameter for direct bore measurement\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch tolerance for precise dimensional control\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and long service life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ minus plug pin gage suitable for use in general-purpose dimensional inspection of machined bores and holes requiring 0.79 inch nominal diameter verification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists and quality control technicians following standard metrology practices. Clean the gage and bore thoroughly before use to prevent false readings caused by debris or oil film. Store the gage in its case when not in use to protect the precision ground surface from damage or corrosion. Do not force the gage into a hole, as this can damage both the gage and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.79 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\u003eClass\u003c\/strong\u003e: 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\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: 19-790-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721124348210,"sku":"19-790-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/98c32d4f5a21d9e83f2fe319a4affb95.jpg?v=1788573933","url":"https:\/\/voomisupply.com\/products\/spi-19-790-5-class-zz-minus-plug-pin-gage-0-79-in","provider":"Voomi Supply","version":"1.0","type":"link"}
