Pin gages are used to verify bore diameters, hole sizes, and slot widths to a precise tolerance. This gage carries a minus tolerance of 0.0002 inches, meaning it is ground to the lower boundary of the nominal size, which allows for go\/no-go inspection workflows common in machining and quality control environments. Machinists, toolmakers, and quality technicians use plug pin gages during in-process and final inspection of machined components.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for shop-floor and inspection room use where accurate hole measurement is required. Class ZZ is a working-grade gage tolerance class appropriate for general inspection of production parts. The 0.325-inch diameter makes it a practical choice for checking holes and bores in that size range on machined metal parts, fixtures, and assemblies. It is a single gage unit sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ minus tolerance — ground to the lower boundary of nominal diameter for go-type inspection use\u003c\/li\u003e\n  \u003cli\u003e0.0002-inch tolerance for precise dimensional verification\u003c\/li\u003e\n  \u003cli\u003e0.325-inch nominal diameter\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop-floor conditions\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for individual replacement or kit supplementing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a working-grade plug pin gage for general inspection of bores and holes at the 0.325-inch nominal diameter in machined components and assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug pin gages are handled and used by machinists and quality control technicians — no power tools or mechanical installation is required. Clean the gage and the bore being checked before use to prevent debris from affecting readings. Store the gage in a protective case away from other tooling to prevent nicks and surface damage. Periodic calibration against a traceable standard is recommended to confirm gage integrity over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.325 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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 19-325-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693817102642,"sku":"19-325-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9a758b7f691e66b51b815092a137b80.jpg?v=1788317747","url":"https:\/\/voomisupply.com\/products\/spi-19-325-0-class-zz-minus-plug-pin-gage-0-325-in","provider":"Voomi Supply","version":"1.0","type":"link"}
