Class ZZ is the standard tolerance grade for general-purpose go\/no-go inspection work in production and shop-floor environments. This gage carries a minus tolerance of 0.0002 inches, meaning the actual gage diameter is held below the nominal. Machinists, quality control technicians, and tool room personnel use pin gages like this one to confirm drilled, reamed, or punched hole sizes quickly and consistently without requiring measurement instruments such as micrometers or bore gages.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for inspection of small-diameter holes in precision machined components, sheet metal fabrication, and tooling verification. At 0.026 inches nominal diameter, it falls in the small-pin range commonly used for checking clearance holes, dowel pin bores, and orifice diameters in fluid control components. It is used in both production line inspection stations and quality lab settings. Individual pins like this one are typically used as part of a pin gage set or as a standalone replacement for a specific size in an existing set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal diameter of 0.026 inches for small-bore inspection applications\u003c\/li\u003e\n  \u003cli\u003eClass ZZ minus tolerance of 0.0002 inches provides controlled undersize fitment for go-gage use\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eSingle-pin format works as a standalone gage or as a replacement in an existing pin set\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds, easy to handle in close-tolerance inspection work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standalone pin for Class ZZ minus pin gage sets requiring a 0.026 inch nominal diameter size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils on the gage surface. Before use, inspect the pin for nicks, burrs, or surface damage that could affect measurement accuracy. Store in a protective case away from other metal tools to prevent contact damage. Calibration and use should follow applicable dimensional inspection procedures in your quality management system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.026 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: 19-026-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714095907122,"sku":"19-026-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e4daa58fcf8129203cf77ffe327eb23.jpg?v=1788496144","url":"https:\/\/voomisupply.com\/products\/spi-19-026-4-class-zz-minus-plug-pin-gage-0-026-in","provider":"Voomi Supply","version":"1.0","type":"link"}
