Plug pin gages are precision measuring tools used to verify hole diameters and bore tolerances in machined parts. This gage is constructed from steel for durability and dimensional stability under shop conditions. Class ZZ designates the tolerance grade appropriate for general-purpose inspection and production floor use. Machinists, quality control technicians, and tool-and-die tradespeople use pin gages like this one to confirm that a drilled or reamed hole falls within an acceptable size range before assembly.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for incoming inspection, in-process quality checks, and final inspection tasks where a 0.458-inch nominal bore must be verified. It is commonly used in metal fabrication shops, machine shops, and manufacturing facilities that work with close-tolerance components. The minus tolerance grind means the gage body measures slightly under nominal, which is the standard configuration for go-gage applications where the gage must pass through an acceptable hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.458 inches for direct bore verification at that size\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance grade for general-purpose production and inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance grind of 0.0002 inches provides a go-gage style fit\u003c\/li\u003e\n  \u003cli\u003eSteel construction for shop-floor durability and long service life\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design with no adjustable components to go out of calibration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose plug pin gage for any inspection or production application requiring verification of a 0.458-inch nominal diameter bore.\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. Before use, verify the gage surface is free of burrs, debris, or damage that could affect measurement accuracy. Store in a protective case away from other tooling to prevent nicks on the ground surface. Periodic recalibration against a certified reference standard is recommended to maintain measurement traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.458 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: Class ZZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Direction\u003c\/strong\u003e: Minus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (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: 19-458-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51716310761778,"sku":"19-458-9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab07a69a824c33ad32853cc9df8b7a17.jpg?v=1788524196","url":"https:\/\/voomisupply.com\/products\/spi-19-458-9-class-zz-minus-plug-pin-gage-0-458-in","provider":"Voomi Supply","version":"1.0","type":"link"}
