The set covers a diameter range of 0.751 to 0.832 inches with a minus tolerance of 0.0002 inches, meeting NIST traceable standards for dimensional accuracy. Constructed from steel, the 82-piece set is well-suited for quality control technicians, machinists, and metrology professionals who require reliable GO and NO-GO gaging inspection without setup-intensive measurement instruments.\u003c\/p\u003e\n\u003cp\u003eThis plug gage set is used in precision machining shops, production inspection lines, and quality assurance labs handling tight-tolerance work. The covered range of 0.751 to 0.832 inches makes it applicable to a wide variety of bored, drilled, or reamed features in both ferrous and non-ferrous workpieces. The set is appropriate for incoming inspection, in-process verification, and final part acceptance in both job-shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance rating with 0.0002 inch minus tolerance for repeatable inspection results\u003c\/li\u003e\n  \u003cli\u003e82-piece set covering 0.751 to 0.832 inches in incremental steps\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop floor and inspection room use\u003c\/li\u003e\n  \u003cli\u003eNIST traceable Certificate of Accuracy included for calibration records\u003c\/li\u003e\n  \u003cli\u003ePin gage holder included for organized storage and quick access\u003c\/li\u003e\n  \u003cli\u003eSuitable for hole size measurement, slot width gauging, and NO-GO inspection applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ plug gage set for precision measurement applications requiring diameter verification in the 0.751 to 0.832 inch range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled by metrology technicians and machinists; no power tools or electrical lockout procedures are required. Keep gage pins clean and lightly oiled when stored to prevent corrosion on the steel surfaces. Handle pins by the holder rather than the gage pin shank to avoid introducing temperature-related dimensional error from body heat. Store the set in the included holder and case away from abrasive materials to preserve surface finish and tolerance integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 0.751 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.832 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: 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: 82\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: 28.44 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 22-151-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691927437618,"sku":"22-151-5","price":513.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617c3ea2d2cf5a61ab18ee858bdecac.jpg?v=1788291121","url":"https:\/\/voomisupply.com\/products\/spi-22-151-5-class-zz-plug-gage-set-0-751-0-832-in-82-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
