Sonic’s 1/2” drive Torque Wrenches are available in a variety of sizes from 20-100Nm (14-73ft/lb) all the way to 80-400Nm (60-295ft/lb). These torque wrenches work in a single direction, accurately measuring the force placed on a fastener in a clock-wise motion. The handle of the wrench turns to adjust the setting, with a magnifying lens built into the handle making the numbers easy to read. A knob at the end of the handle keeps it locked during use and easily pops out for adjustment for the next fastener.
