The Pistol Grip Tool is a self-contained, computer- controlled, battery-powered 3/8 inch drive power tool with a pistol-style handle. Numerous torque, speed and turn limits can be programmed into the tool for mission-specific applications. A light emitting diode display on the tool tells the astronaut what torque he or she is applying, at what speed, and how many turns the motor has made. It also displays error messages. The motorized torque ranges from 2 to 25 foot-pounds, the speed from 5 to 60 rotations per minute, and the number of turns from 0 to 999. In manual mode, the Pistol Grip Tool can apply 38 foot-pounds of torque. The specifications for every fastener are preprogrammed into the PGT before each mission and the PGT then logs the actual data during EVA.
