Covering a diameter range of 0.011 to 0.06 inches with a plus tolerance of 0.0002 inches (0.0002 mm), this set delivers the accuracy required for GO gaging and general inspection work. The gages are manufactured from steel and ship with a Certificate of Accuracy backed by NIST traceability. A pin gage holder is included. Machinists, quality technicians, and tool-and-die professionals rely on sets like this for fast, repeatable dimensional verification on the shop floor or in the inspection lab.\u003c\/p\u003e\n\u003cp\u003eThis plug gage set is suited for production inspection and quality control environments where quick, accurate measurement of small bores and slots is required. Typical applications include verifying drilled or reamed hole diameters, checking slot widths on machined components, and calculating distances between holes. The Class ZZ tolerance designation indicates a working-gage grade appropriate for general inspection use rather than master or reference gaging. The set is packaged as a single unit and is ready to use out of the box with the included holder and certificate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e50-piece set covering 0.011 to 0.06 inches diameter range\u003c\/li\u003e\n  \u003cli\u003eClass ZZ tolerance grade with plus tolerance of 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003eNIST traceable Certificate of Accuracy included\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003ePin gage holder included for organized storage and use\u003c\/li\u003e\n  \u003cli\u003eSupports GO gaging inspection, hole sizing, slot width measurement, and hole-distance calculation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class ZZ working plug gage set for use with any pin gage holder accepting the included diameter range; compatible with common inspection fixtures and gage blocks used in general machining and quality control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages should be handled by quality technicians or machinists familiar with dimensional inspection procedures. Clean the gages and the workpiece bore before use to avoid false readings caused by debris or residual coolant. Store gages in the provided holder when not in use to prevent nicks or corrosion that would affect accuracy. Periodic recalibration against a NIST traceable standard is recommended per your facility quality management program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 0.011 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\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: 50\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 Dimensions\u003c\/strong\u003e: 8.46 inches L x 6.3 inches W x 2.64 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.88 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: 22-170-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715377561906,"sku":"22-170-5","price":84.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1c74998024f089236873ea58e9e0d0f.jpg?v=1788513031","url":"https:\/\/voomisupply.com\/products\/spi-22-170-5-class-zz-plug-gage-set-50-pc-nist-traceable","provider":"Voomi Supply","version":"1.0","type":"link"}
