Featuring a 3\/4 inch drive and a fixed head, it delivers precise electronic torque measurement across a range of 60 to 600 foot-pounds (81 to 813 Nm). Graduations are set at 0.1 Nm and 1 foot-pound increments, giving technicians consistent, repeatable readings on critical fastener installations. At 12.37 pounds and 22 inches in overall length, the J6347 is sized for torque-critical work where analog tools fall short of the required accuracy.\u003c\/p\u003e\n\u003cp\u003eThe J6347 is suited for heavy-duty mechanical service work including drivetrain assembly, flange bolting, structural fastening, and equipment maintenance where torque verification is required by procedure or specification. The 3\/4 inch drive accepts standard impact sockets and extensions, making it compatible with common shop setups across automotive, fleet, industrial, and construction service environments. This tool is a fit for professional mechanics, millwrights, and heavy equipment technicians who require a documented torque value rather than a click-style approximation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDigital readout with 0.1 Nm and 1 foot-pound graduation for precise torque measurement\u003c\/li\u003e\n  \u003cli\u003eWide torque range: 60 to 600 foot-pounds (81 to 813 Nm) covers a broad set of fastener applications\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch fixed head drive for compatibility with standard heavy-duty sockets and extensions\u003c\/li\u003e\n  \u003cli\u003e22 inch overall length provides leverage for high-torque fastening tasks\u003c\/li\u003e\n  \u003cli\u003eMaximum torque output of 7,200 inch-pounds for applications specified in that unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/4 inch drive sockets and accessories across professional mechanical and industrial service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDigital torque wrenches should be used by qualified mechanical technicians following applicable fastener torque specifications from the equipment manufacturer or relevant service standard. Always zero the wrench and verify calibration before use on torque-critical fasteners. Do not use this wrench as a breaker bar or for loosening fasteners, as this can damage the internal electronics. Store the tool at a reduced torque setting when not in use to preserve internal load cell accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Type\u003c\/strong\u003e: Digital Torque Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Torque\u003c\/strong\u003e: 60 foot-pounds (81 Nm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 600 foot-pounds (813 Nm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Torque (inch-pounds)\u003c\/strong\u003e: 7,200 in\/lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.1 Nm \/ 1 foot-pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 12.37 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\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: PROTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J6347\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542904668466,"sku":"J6347","price":2400.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b2f0262e8297834be154ebc8d1fffc4.jpg?v=1785910478","url":"https:\/\/voomisupply.com\/products\/proto-j6347-digital-torque-wrench-3-4-inch-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
