This single-ended pin gage is used to check hole sizes and bore diameters to a tolerance of 0.000200 inches, confirming whether a feature falls within acceptable limits. Class ZZ designates a general-purpose commercial tolerance grade suitable for inspection of production parts. Machinists, quality control technicians, and toolroom personnel rely on pin gages like this one to maintain dimensional standards on the shop floor or in the inspection lab.\u003c\/p\u003e\n\u003cp\u003eThis pin gage is suited for dimensional inspection tasks in manufacturing, machining, and quality assurance environments. It is used to verify drilled, reamed, or bored hole diameters on metal components where close tolerances must be confirmed before parts advance in production. The minus designation indicates the gage is ground to the lower limit of the nominal size, which follows standard GO gage practice for checking minimum acceptable hole sizes. This gage is appropriate for use in both production floor checks and bench inspection setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance grade for general-purpose commercial inspection use\u003c\/li\u003e\n  \u003cli\u003eMinus designation ground to the lower tolerance limit of the nominal diameter\u003c\/li\u003e\n  \u003cli\u003e0.416 inch nominal diameter for direct hole and bore verification\u003c\/li\u003e\n  \u003cli\u003e0.000200 inch tolerance for reliable dimensional confirmation\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and wear resistance in shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ minus plug pin gage for use with standard pin gage handles and holders that accept 0.416 inch diameter gage pins in typical toolroom and inspection applications.\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. Before use, inspect the gage surface for burrs, nicks, or wear that could affect accuracy. Store pin gages in a protective case away from other metal tools to prevent surface damage. Calibration should be verified against a certified master reference at intervals consistent with your quality management system requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.416 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\u003c\/strong\u003e: 0.000200 inches (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: 19-416-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51718036095282,"sku":"19-416-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/086f22952392b7e743f48f8a20192b70.jpg?v=1788548840","url":"https:\/\/voomisupply.com\/products\/spi-19-416-7-class-zz-minus-plug-pin-gage-0-416-in","provider":"Voomi Supply","version":"1.0","type":"link"}
