This gage is used to verify hole diameters and internal bore dimensions by checking whether a feature will accept the pin. Class ZZ is the standard tolerance grade for production-floor inspection work, and the minus designation means the gage is ground to the lower end of the tolerance band. With a tolerance of 0.0002 inches, this pin provides repeatable go\/no-go verification suitable for quality control applications in manufacturing, machining, and precision assembly operations. Licensed machinists, quality technicians, and tool-and-die professionals are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis plug pin gage is used in production and inspection environments where internal diameter verification is required. It is suited for checking drilled, reamed, or bored holes in metal, plastic, or composite workpieces. The 0.357-inch size fits a common range of machined features encountered in general manufacturing and precision fabrication. It is appropriate for both incoming inspection and in-process quality checks on the shop floor or in a metrology lab setting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance grade for production-floor go\/no-go inspection\u003c\/li\u003e\n  \u003cli\u003eMinus designation ground to the lower tolerance limit for consistent fit verification\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for reliable dimensional acceptance criteria\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance during repeated use\u003c\/li\u003e\n  \u003cli\u003e0.357-inch nominal diameter for direct hole-size verification\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 standard go\/no-go inspection applications requiring a 0.357-inch Class ZZ minus diameter gage.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by quality technicians and machinists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain dimensional integrity. Do not force the pin into a feature; excessive insertion force can damage the gage or the workpiece and will not produce a valid measurement. Store in a protective case away from temperature extremes to preserve calibration accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.357 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: 19-357-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689650880818,"sku":"19-357-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de86a28acaea8360e458dd78d5e80222.jpg?v=1788262433","url":"https:\/\/voomisupply.com\/products\/spi-19-357-3-class-zz-minus-plug-pin-gage-0-357-in","provider":"Voomi Supply","version":"1.0","type":"link"}
