The set contains 250 individual pin gages and is designed for fast, repeatable measurement of hole sizes, slot widths, and center-to-center distances between holes. It also supports NO-GO gaging inspection workflows. Each set ships with a Certificate of Accuracy that is NIST traceable, making it suitable for quality control environments where documented traceability is required. The set weighs 16.09 pounds and is packaged in a case measuring 17.72 inches long by 12.2 inches wide by 2.83 inches tall.\u003c\/p\u003e\u003cp\u003eThis plug gage set is used in machine shops, inspection departments, and manufacturing facilities where precise hole qualification is part of standard workflow. Machinists, quality technicians, and tool-and-die professionals reach for sets like this when verifying bores, checking fitment tolerances, and performing incoming or in-process inspection. The 250-piece range from 5 mm to 9.98 mm covers a broad span of small-to-medium hole sizes commonly encountered in precision metalworking and fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ tolerance classification with minus 0.005 mm tolerance per pin\u003c\/li\u003e\n\u003cli\u003e250-piece set spanning 5.000 mm to 9.98 mm diameter range\u003c\/li\u003e\n\u003cli\u003eSuitable for hole size measurement, slot width measurement, and NO-GO gaging inspection\u003c\/li\u003e\n\u003cli\u003eIncludes Certificate of Accuracy with NIST traceable standards\u003c\/li\u003e\n\u003cli\u003eIncludes pin gage holder\u003c\/li\u003e\n\u003cli\u003eCase dimensions: 17.72 inches long by 12.2 inches wide by 2.83 inches tall\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in precision measurement and inspection applications requiring Class ZZ plug gages in the 5 mm to 9.98 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and measurement error from skin oils. Store pins in the provided case when not in use to protect precision-ground surfaces. Verify the appropriate pin size against your print tolerance before use, and never force a pin gage into a hole, as this can damage both the gage and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 5.000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 9.98 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: -0.005 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Type\u003c\/strong\u003e: Minus\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: 250\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: 17.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 12.2 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: 16.09 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: 22-180-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51712272105778,"sku":"22-180-4","price":297.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b68bab8b99295d9a1a7ded8012de184d.jpg?v=1788485850","url":"https:\/\/voomisupply.com\/products\/spi-22-180-4-class-zz-plug-gage-set-250-pc-5-9-98mm","provider":"Voomi Supply","version":"1.0","type":"link"}
