Pin gages are precision go\/no-go measurement tools used to verify hole diameters, slot widths, and bore sizes to a known dimensional standard. This gage is machined from steel and held to Class ZZ tolerances, which are the standard for general-purpose inspection and production floor use. Machinists, quality technicians, and tool-and-die professionals use plug gages like this one to confirm that drilled, reamed, or bored features fall within acceptable dimensional limits before parts move to the next operation.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in machine shops, fabrication facilities, and inspection departments where hole-size verification is part of a standard quality control workflow. The 0.479 inch diameter and Class ZZ minus tolerance make it appropriate for checking features produced to close dimensional callouts. It is a single-pin gage intended for bench use or in-process inspection. The compact size and light weight at 0.2 pounds make it easy to handle during repetitive inspection tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance: 0.0002 inches for general-purpose inspection accuracy\u003c\/li\u003e\n  \u003cli\u003eNominal diameter of 0.479 inches for precise hole and bore verification\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability during repeated use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds, suitable for bench and floor inspection tasks\u003c\/li\u003e\n  \u003cli\u003eMinus designation indicates the gage is ground below nominal, consistent with go-gage applications\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 any inspection setup requiring a Class ZZ minus gage at 0.479 inch nominal diameter.

Keep the gage surface clean and lightly oiled to prevent corrosion and maintain dimensional integrity. Do not force the gage into a feature; apply only light hand pressure to avoid burring or deflecting the gage pin. Calibration interval should follow your facility's quality management procedures or applicable ASME B89 standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.479 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\u003eTolerance (mm)\u003c\/strong\u003e: 0.0002 mm\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: 19-479-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51697029087538,"sku":"19-479-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d0602e52468b2b67901b0e4444e337d.jpg?v=1788348621","url":"https:\/\/voomisupply.com\/products\/spi-19-479-5-class-zz-minus-plug-pin-gage-0-479-in","provider":"Voomi Supply","version":"1.0","type":"link"}
