ABSTRACT:
A rotary impact tool such as a socket wrench has an anvil member at one end of a shaft for providing rotary movement to a tool body, and a striker non-rotatably and slidably mounted on the shaft for impacting the anvil member and imparting rotational forces thereto through complementary inclined striking surfaces on the anvil member and striker, respectively. The anvil member is mounted for limited rotational movement on the shaft between first and second extreme positions and can be biased to one or other of such positions to properly orientate the respective striking surfaces of the anvil and striker members.
