The Apollo toolset provides multipurpose tools and/or attachments for mechanical actuations and valve adjustments. This component is labeled: Tool V - U-Joint Driver. The U-joint driver has a 7/16-inch driver socket at one end and a universal joint with a small and a large hex drive at the other end. The U-joint driver will rotate up to an angle of 30°. It is used to gain access to the "hard to get at" fasteners.
This set was used during the Apollo 11 mission and NASA transferred it to the Smithsonian in 1970.
