The set covers a diameter range of 0.061 to 0.25 inches with a plus tolerance of 0.000200 inches, making it suitable for verifying hole sizes, slot widths, and distances between holes. Gages are manufactured from steel for durability and wear resistance. A Certificate of Accuracy with NIST-traceable calibration and a pin gage holder are included with the set. This tool is a standard choice for machinists, quality technicians, and toolroom professionals who need reliable GO gaging inspection capability.\u003c\/p\u003e\u003cp\u003eThis plug gage set is used in manufacturing, toolroom, and inspection environments where accurate bore and hole verification is required. The 190-piece range spanning 0.061 to 0.25 inches covers a wide variety of common hole sizes encountered in general metalworking and mechanical assembly. The included pin gage holder keeps pins organized and accessible during use. Typical applications include incoming inspection, in-process quality checks, and final part verification across both job shop and production floor settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e190-piece set covering 0.061 to 0.25 inches diameter range\u003c\/li\u003e\n\u003cli\u003eClass ZZ tolerance of 0.000200 inches (plus tolerance type)\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in toolroom and inspection use\u003c\/li\u003e\n\u003cli\u003eIncludes Certificate of Accuracy with NIST-traceable calibration\u003c\/li\u003e\n\u003cli\u003ePin gage holder included for organized storage and quick access\u003c\/li\u003e\n\u003cli\u003eSuitable for GO gaging, hole sizing, slot width measurement, and distance-between-holes calculations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose Class ZZ plug gage set for use in standard GO gaging inspection workflows across a wide range of metalworking and mechanical assembly applications where hole diameters between 0.061 and 0.25 inches require verification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are typically handled by quality technicians or machinists and require no permanent installation. Store pins in the provided holder and handle with clean, dry hands or lint-free gloves to prevent corrosion and dimensional error from contamination. Verify gage pins against the included NIST-traceable certificate periodically to confirm calibration status. Follow your facility quality management procedures for gage control and calibration intervals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 0.061 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.000200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Type\u003c\/strong\u003e: Plus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: ZZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 190\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NIST Traceable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 13.19 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 9.84 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 2.83 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.19 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 22-171-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721330098482,"sku":"22-171-3","price":158.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/331d8d2e20352edf8515f5fd78bc4c5e.jpg?v=1788576561","url":"https:\/\/voomisupply.com\/products\/spi-22-171-3-class-zz-plug-gage-set-190-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
