With a nominal diameter of 0.079 inches and a tolerance of 0.0002 inches, this gage provides the dimensional accuracy required for quality control checks in machining, fabrication, and assembly environments. Constructed from steel, the 19-079-3 is built to withstand repeated use in shop-floor conditions. Machinists, quality technicians, and tool-and-die professionals use Class ZZ minus gages as an economical solution for checking hole size conformance on production and inspection work.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug gages are suited for general-purpose inspection of drilled, reamed, and bored holes in both production and maintenance settings. The minus designation indicates the gage is ground to the lower end of the tolerance range, making it appropriate for checking hole acceptance when tight dimensional control is required. This gage fits standard gage handle holders and integrates into existing pin gage sets used in light manufacturing, tool rooms, and quality inspection departments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.079 inches for precise hole inspection\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance grade rated at 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003eMinus designation for lower-end tolerance conformance checking\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated shop-floor use\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard pin gage handle holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug pin gage for general-purpose hole inspection applications requiring a 0.079-inch nominal diameter Class ZZ minus gage.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Insert the gage into the inspection hole with light, consistent hand pressure — never force the gage, as this can damage both the gage and the workpiece. Store the gage in its designated case or holder when not in use to protect the ground surface from nicks and wear. Periodic cleaning and light oiling per standard metrology practice will help maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.079 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: 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: 19-079-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720971026738,"sku":"19-079-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bf06f968aec59a4e78a5176903da1f0.jpg?v=1788571649","url":"https:\/\/voomisupply.com\/products\/spi-19-079-3-class-zz-minus-plug-pin-gage-0-079-in","provider":"Voomi Supply","version":"1.0","type":"link"}
