ACDelco ARM601-4 Electronic Torque Wrench

Electronic Torque Wrenches can be complicated, but this is not one of them. The ACDelco ARM601-4 Electronic Torque Wrench offers a simple approach to moving away from the old beam or click-style torque wrench. From the LCD screen and four pushbuttons, users can choose measurements from in-lbs, ft-lbs, Nm, and kg-cm. You can also select from Peak (P) and Trace (T) modes for momentary torque readings.

At just over 17-inches long, the ACDelco ARM601-4 offers a compact size for a 1/2″ torque wrench. Also, the torque range from 15 to 150 ft-lbs lands in more of a mid-range. Many of the 1/2″ torque wrenches on the market deliver 50-250 ft-lbs, as well as measuring more than 24″. While these larger torque wrenches are great for wheels and tires, they miss the mark on the lower end. This ACDelco electronic torque wrench size and range is a perfect fit for most internal engine and suspension components.
