The Mega Torque Wrench from Jones Stephens allows users to obtain a proper, leak-free seal on no hub couplings. This professional grade wrench is preset to 80 in. lbs. torque with a 5/16 in. hex head. Using the ratcheting action, when the fitting is tightened to the correct torque it will stop and click. For added convenience, use the built-in sliding lock feature as a nut driver to loosen no hub clamps and remove couplings. This torque wrench is designed for one-handed tightening and features a large, comfortable t-handle containing all mechanisms and lubrication for long-life and durability.
