The Powerbuilt 1/2" Drive Deflecting Beam Torque Wrench, from Alltrade Tools, offers the accuracy, durability and repeatability that busy technicians and shops appreciate. With a unique deflecting beam design, torque is loaded into the beam instead of a coil spring, ensuring accurate results over thousands of uses in a broad range of temperatures and work environments. When the target torque is reached, both audible and visual signals are produced, making it ideal for loud shops. The sliding torque selector is easier to read and faster to set than a micrometer style wrench, according to the company. The wrench provides a wide torque range of 20 ft/lbs to 220 ft/lbs, for added versatility.
