Pin gages in this class are used to verify hole diameters, check slot widths, and confirm feature sizes on machined parts during inspection and quality-control operations. The minus designation means the gage is ground to the low side of the nominal diameter, which is the standard for go\/no-go inspection workflows. Constructed from steel, this gage is a straightforward hand tool used by machinists, quality technicians, and tool-and-die professionals on the shop floor or in inspection departments.\u003c\/p\u003e\n\u003cp\u003eClass ZZ plug pin gages are the general-purpose grade used in production inspection environments where tight-tolerance measurement is required but Class Z or ZZ-plus precision is not specified. The 19-456-3 is suited for checking 0.456-inch diameter features in metal, plastic, or composite workpieces. It is typically used at receiving inspection stations, in-process QC checks, or final part verification. The compact form factor and 0.2-pound weight make it easy to handle during high-volume inspection tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance grade for standard production inspection use\u003c\/li\u003e\n  \u003cli\u003e0.456-inch nominal diameter for direct hole and feature verification\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches for consistent, repeatable go\/no-go checks\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for comfortable single-hand operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard addition to Class ZZ pin gage sets used in production and inspection applications requiring a 0.456-inch diameter plug gage.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages require no installation but should be handled by quality technicians or machinists familiar with go\/no-go inspection procedures. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Do not force the gage into a feature that does not accept it freely, as this can damage the gage surface and compromise measurement accuracy. Handle with clean gloves or a gage cloth to avoid introducing thermal expansion errors from hand contact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.456 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: 19-456-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690685301042,"sku":"19-456-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8632aa7cf5a3d853e2ebbb82763da6b.jpg?v=1788273929","url":"https:\/\/voomisupply.com\/products\/spi-19-456-3-class-zz-minus-plug-pin-gage-0-456-in","provider":"Voomi Supply","version":"1.0","type":"link"}
