ABSTRACT:
A hand tool for turning sockets connectable to nuts and bolts has a handle attached to a head having an inside cylindrical surface. A body joined to a member for holding a socket has a plurality of pockets facing the cylindrical surface and chord ramps at the bottom of the pockets. Rollers located in the pockets engage the ramps and cylindrical surface to selectively lock and unlock the head to the body so that when the handle is oscillated the body intermittently rotates. A ring mounted on the body is manually moved to shift the rollers between opposite end sections of the pockets. A socket release ball mounted on the member is controlled by a stem movably mounted on the body and member.
