A power-driven hand tool (11) including a housing (23) having first and second housing parts (42, 43) having first and sec- ond coaxial openings (54, 55) therethrough. A driving element (37) is movably positioned between the housing parts (42, 43) and has a third opening (38) in coaxial alignment between the first and second openings (54, 55). A motor (28) is mounted on the housing (23) and connects through a motion-transfer device to the driving element (37) for causing angular oscillation thereof about a tool-driving axis. An annular socket-driving member (52) is rotatably supported within the first opening (42) and has a bore (66) therethrough coaxial with the axis for releasably but drivingly engaging a removable socket (14). The socket-driving member (52) has a gear (63) rotatably positioned in the third opening (38). First and second pawls (84, 85) are mounted on the driving element (37) for engagement with the gear (63) for respectively causing rotational driving movement of the socket in oppo- site first and second directions. A reversing member (53) cooperates with the pawls (84, 85) and is movable between first and sec- ond positions for respectively permitting solely the first and second pawls (84, 85) to be drivingly engaged with the gear (63).
