The 0.022-inch nominal diameter and minus tolerance grind of 0.000200 inches make this gage suitable for verifying tight-tolerance features in precision machined parts. Class ZZ is the standard commercial-grade designation for plug gages used in general inspection work rather than master or reference applications. Machinists, quality technicians, and tool-room personnel use this type of gage for production floor and incoming inspection tasks.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is used in precision manufacturing environments where hole diameter verification is required on small-bore features. Typical applications include inspection of drilled, reamed, or punched holes in metal, plastic, and composite workpieces. The 0.022-inch size is common in fine-pitch fastener applications, electronics hardware, and instrument components. The minus tolerance grind ensures the gage sits at or below nominal, consistent with standard go-gage practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class for general commercial inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance grind at 0.000200 inches for consistent go-gage application\u003c\/li\u003e\n  \u003cli\u003e0.022-inch nominal diameter for small-bore inspection\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity 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 standard Class ZZ minus plug pin gage for use with conventional pin gage handles and holders accepting 0.022-inch diameter pins in general-purpose inspection setups.\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 that can affect dimensional accuracy. Insert the pin gage into the feature being inspected with light, consistent hand pressure — never force the pin. Store pin gages in a protective case away from other metal tools to prevent surface damage. Calibration should be verified against a traceable standard at regular intervals per your facility quality plan.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.022 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: 0.000200 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: 19-022-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51711929844018,"sku":"19-022-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/831e59607518a5073286bbd4f020b100.jpg?v=1788481534","url":"https:\/\/voomisupply.com\/products\/spi-19-022-3-class-zz-minus-plug-pin-gage-0-022-in","provider":"Voomi Supply","version":"1.0","type":"link"}
