Built from steel, this fixed-limit gage delivers a tolerance of 0.0002 inches, making it suitable for production inspection and quality control applications where consistent dimensional verification is required. Machinists, tool-and-die makers, and quality technicians use plug gages like this one to confirm whether a drilled, reamed, or bored hole falls within specification. The go\/no-go style of measurement eliminates reliance on variable gauging and speeds up high-volume part inspection.\u003c\/p\u003e\n\u003cp\u003eThis gage is well suited for use in machine shops, manufacturing facilities, and production environments where hole diameter conformance must be verified quickly and reliably. The Class ZZ Plus designation places it in the working gage category, appropriate for shop-floor inspection rather than master or reference applications. Its compact, lightweight form allows easy handling during routine part checks on a variety of workpiece materials and configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal measurement diameter of 0.682 inches for precise bore verification\u003c\/li\u003e\n  \u003cli\u003eTolerance of 0.0002 inches supports accurate Class ZZ Plus working-gage performance\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability for repeated shop-floor use\u003c\/li\u003e\n  \u003cli\u003eFixed-limit design speeds up go\/no-go inspection without variable gauging\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.2 pounds for easy single-hand operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style working plug gage for use in standard bore and hole inspection applications requiring a 0.682-inch nominal diameter measurement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists and quality control technicians — no installation in a mechanical system is required. Before use, clean both the gage and the workpiece bore to remove chips, coolant, and debris that can affect measurement accuracy. Store the gage in its protective case when not in use to prevent damage to the ground and lapped surfaces. Calibration intervals should follow your facility quality management procedures to maintain measurement traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.682 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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Class\u003c\/strong\u003e: ZZ Plus\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: 29-682-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698956370226,"sku":"29-682-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bbf403dd8a93990d3f0bd3dd50eaad4.jpg?v=1788370333","url":"https:\/\/voomisupply.com\/products\/spi-29-682-2-class-zz-plus-plug-gage-0-682-in","provider":"Voomi Supply","version":"1.0","type":"link"}
