The set includes 84 steel pin gages calibrated to a plus tolerance of 0.0002 inches, making it suitable for precise hole inspection and dimensional verification in production and quality control environments. Each gage is NIST traceable and ships with a Certificate of Accuracy. Licensed metrology technicians, machinists, and quality inspectors use this set to verify hole sizes, slot widths, and center-to-center distances quickly and reliably without the need for electronic measurement instruments.\u003c\/p\u003e\u003cp\u003eThis plug gage set is used in manufacturing, machine shops, and inspection departments where hole diameter verification is a routine task. The 0.833 to 0.916 inch range makes it well suited for medium-bore inspection work on machined components. The set supports GO gaging inspection applications, allowing technicians to confirm whether a hole or slot falls within acceptable dimensional limits. The included pin gage holder keeps individual gages organized and protected between uses, supporting efficient workflow on the shop floor or at an inspection station.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass ZZ tolerance classification with a plus tolerance of 0.0002 inches for precision inspection work\u003c\/li\u003e\n\u003cli\u003eMeasurement range of 0.833 to 0.916 inches covering medium-bore hole sizes\u003c\/li\u003e\n\u003cli\u003e84-piece set providing incremental coverage across the full range\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and dimensional stability under shop conditions\u003c\/li\u003e\n\u003cli\u003eNIST traceable Certificate of Accuracy included with each set\u003c\/li\u003e\n\u003cli\u003eSupports GO gaging inspection, hole size measurement, slot width measurement, and distance-between-holes calculation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Class ZZ plug gage set for use in general machined-component inspection applications where ANSI pin gage standards apply.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are handled and used by quality inspectors and machinists; no installation in the mechanical sense is required. Store gages in the provided holder and keep them clean and lightly oiled to prevent corrosion and dimensional drift. Do not force a gage into a hole that offers significant resistance, as this can damage both the gage and the workpiece. Follow your facility's gage calibration interval procedures to maintain NIST traceability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 0.833 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.916 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 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: 84\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: 17.72 inches L x 12.2 inches W x 2.83 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 34.17 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: 22-176-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714587328818,"sku":"22-176-2","price":604.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a87ee8f67bb7fa4bdaa8e3c5e6cac448.jpg?v=1788503518","url":"https:\/\/voomisupply.com\/products\/spi-22-176-2-class-zz-plug-gage-set-84-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
