Collection Item Summary:
The high-torque Right Angle Drive tool (RAD 10-20) was developed for EVA tasks on the Shuttle-Mir docking adapter but also proved useful for Hubble Space Telescope servicing and other missions, giving the astronauts access to obstructed bolts that could not be readily seen or reached. The drive tool attaches at the shaft end to either the pistol-grip power tool or the palm-wheel mechanical wrench from the standard EVA tool kit, and at the drive end it has a 3/8-inch square interface for a socket tool. It has a 2 to 1 torque multiplication for 80 ft. lbs. torque. The tool was first used on the STS-82 Space Shuttle mission in 1997 and became part of the EVA tool kit for subsequent missions.
This tool is an unflown duplicate. NASA transferred it to the Museum in 2001.
