Fitted with a 1\/2 inch drive and a fixed head, it measures torque from 25 foot-pounds (340 Nm maximum) with a graduation of 0.1 Nm and 1 foot-pound increments, giving technicians accurate, repeatable readings without guesswork. At 22 inches overall length and 4.83 pounds, it balances reach and control for sustained use on mechanical assemblies, equipment installations, and structural fastening tasks. HVAC, plumbing, and mechanical contractors rely on this class of wrench wherever torque specifications are critical to joint integrity and code compliance.\u003c\/p\u003e\u003cp\u003eThe J6346 suits residential and commercial installation work where fastener torque must be documented or verified against manufacturer specifications. It is appropriate for use on equipment mounting hardware, flanged connections, compressor hold-down bolts, and similar applications requiring controlled torque within the 25 to 250 foot-pound range. Its digital readout eliminates the interpretation error common with beam-style or click-type wrenches, making it a preferred tool for technicians working to precise OEM torque requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDigital torque measurement with 0.1 Nm and 1 foot-pound graduation for high-resolution readings\u003c\/li\u003e\n\u003cli\u003e1\/2 inch drive accepts standard sockets and drive accessories\u003c\/li\u003e\n\u003cli\u003eTorque range: 25 to 250 foot-pounds (34 to 340 Nm), covering a wide range of fastening applications\u003c\/li\u003e\n\u003cli\u003eFixed head design for consistent socket engagement and repeatable torque delivery\u003c\/li\u003e\n\u003cli\u003e22 inch overall length provides mechanical advantage and access in typical equipment bays\u003c\/li\u003e\n\u003cli\u003eFoot-pound and Newton-meter measurement modes to match specification sheets in either unit system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2 inch drive sockets and accessories across mechanical, HVAC, plumbing, and general trade fastening applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDigital torque wrenches are typically used by licensed HVAC technicians, plumbers, and mechanical contractors during equipment installation and maintenance. Always power down or de-energize equipment and relieve any system pressure before applying a torque wrench to pressurized fittings or live equipment. Store the wrench at or near minimum torque setting when not in use to preserve internal calibration. Periodic re-calibration is recommended per the manufacturer service interval to maintain measurement accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Torque\u003c\/strong\u003e: 25 foot-pounds (34 Nm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 250 foot-pounds (340 Nm)\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\u003eHead Type\u003c\/strong\u003e: Fixed\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: 4.83 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Measurement Type\u003c\/strong\u003e: Foot Pound \/ Newton-meter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: J6346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51539446858034,"sku":"J6346","price":1087.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18b63ba3d91c7e196d56b98cd9bdece6.jpg?v=1785840442","url":"https:\/\/voomisupply.com\/products\/proto-j6346-digital-torque-wrench-1-2-inch-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
