The changeable sockets are stowed on an EVA tool board and use a drop proof replacement scheme requiring no additional tethering steps. The TMs are designed to provide a positive capture to the reaction fitting and then interface with the power tool or ratchet wrench for the input torque. The right angle drive may also be used between the EVA power tool and the TM. 22.214.171.124 INTERFACE DESCRIPTION The TMs interface and transfer reaction torque to an ORU or to the Space Station structure through a reaction feature compatible with the MCF and Micro robotic interfaces. The TMs provide a torque ratio of 5:1 (output to input) with a tolerance of plus or minus 10%. The TMs interface with the standard EVA 3/8 in. drive ratchet wrench or the EVA power tool. They transmit torque equally in forward and reverse directions....
