It measures 0.616 inches in diameter and is manufactured from steel for durability and dimensional stability. The minus tolerance designation means the gage is ground below nominal, making it suitable for go-gage applications where confirming minimum acceptable hole size is the objective. With a tolerance of 0.0002 inches, this gage meets Class ZZ standards appropriate for general-purpose inspection in shop-floor and quality-control environments. Machinists, tool-and-die makers, and quality technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is used in manufacturing, fabrication, and inspection settings where hole diameter verification is required. It is appropriate for checking drilled, reamed, or bored holes in metal, plastic, or composite workpieces. Class ZZ gages are the standard choice for production-floor go\/no-go inspection routines and are commonly used with gage blocks or gage-pin sets to establish reference measurements. The 19-616-2 is suited for both standalone use and as part of a larger pin gage assortment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.616 inches nominal diameter for direct hole size verification\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance ground to 0.0002 inches below nominal\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eSuitable for go-gage applications in production inspection\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling\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 for use in general-purpose hole inspection applications requiring a 0.616-inch nominal diameter reference.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists and quality inspection personnel, not installed in the traditional sense. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain accuracy. Do not force the gage into a hole; if resistance is felt, the bore is undersize. Store in a protective case away from temperature extremes to preserve calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.616 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 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\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: 19-616-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699900186930,"sku":"19-616-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5619eab21bde5d4a2b2ea3e55bd4346b.jpg?v=1788382851","url":"https:\/\/voomisupply.com\/products\/spi-19-616-2-class-zz-minus-plug-pin-gage-0-616-in","provider":"Voomi Supply","version":"1.0","type":"link"}
