Pistol-Grip Torque-Measuring Power Tool

The figure shows one aspect of the exterior appearance of a pistol-grip torque-measuring power tool. The tool is a self-contained, computer controlled, 3/8-in. (~9.5-mm) drive pistol-grip style tool. The tool is intended for use in assembly operations in which application of precise torques to fasteners is critical to safety. In comparison with controlled-torque industrial and commercial power tools now in use, the tool offers advantages of small volume and more precise control of torque. It can also be operated under battery power, with battery life extended relative to battery lives of similar commercial power tools.
