The set covers a measurement range of 0.0197 to 0.0394 inches (0.500 to 1.00 mm) with a bilateral tolerance of plus or minus 0.002000 inches. Each gage is double-ended, providing two measuring members per handle for increased efficiency during inspection work. The gages are constructed from steel for durability and dimensional stability under typical shop conditions. This set is appropriate for machinists, toolmakers, and quality technicians who require reliable go\/no-go verification of small-diameter holes and bores.\u003c\/p\u003e\u003cp\u003eThis plug gage set is suited for precision inspection of small-diameter holes in production machining, fabrication, and toolroom environments. The Class ZZ tolerance classification is standard for inspection and working gages in light-duty and general-purpose inspection tasks. The set is applicable wherever consistent hole-size verification is required across a range of 0.0197 to 0.0394 inches, including verification of drilled, reamed, or broached bores in metal and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e51-piece set covering 0.0197 to 0.0394 inch diameter range\u003c\/li\u003e\n\u003cli\u003eClass ZZ tolerance classification for general-purpose inspection use\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two gage members per handle\u003c\/li\u003e\n\u003cli\u003eBilateral tolerance of plus or minus 0.002000 inches\u003c\/li\u003e\n\u003cli\u003eSteel construction for dimensional stability and wear resistance\u003c\/li\u003e\n\u003cli\u003eCovers metric equivalent range of 0.500 to 1.00 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style working gage set for general-purpose hole and bore inspection in toolroom and production quality-control settings where Class ZZ plug gages are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages should be handled and stored by trained metrology or toolroom personnel following standard gage-care practices. Clean hole surfaces before gauging to prevent debris from affecting readings or damaging gage surfaces. Do not force gages into holes; apply only light, consistent hand pressure to avoid wear or damage to the gage members. Periodic calibration against a traceable standard is recommended to maintain measurement integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 0.0197 inches (0.500 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.0394 inches (1.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: plus or minus 0.002000 inches (0.0020 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: ZZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Type\u003c\/strong\u003e: Bilateral (Minus\/Plus)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 13.58 inches length x 9.45 inches width x 3.15 inches height\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.31 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: 616-62012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51693832208690,"sku":"616-62012","price":107.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4481731ac043b90397b02bc223a9552.jpg?v=1788317960","url":"https:\/\/voomisupply.com\/products\/spi-616-62012-class-zz-plug-gage-set-51-pc-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
