Abstract: A socket and ratchet combination includes a socket element and a ratchet device or module. The ratchet device is a self-contained ratchet device module having a housing that houses a ratchet mechanism, and the socket element includes a passageway that is configured to receive the housing of the ratchet device therein. When a drive member of a lever arm is connected to the ratchet device and the lever arm is rotated in a first direction, the ratchet device and the socket element rotate in the first direction to rotatably drive a fastener at least partially received at an end region of the socket element, and when the drive member of the lever arm is connected to the ratchet device and the lever arm is rotated in a second direction, the ratchet device allows the lever arm to rotate in the second direction relative to the socket element.

Abstract: A wrench for applying a drive torque at a drive element includes an elongated handle, a clamping element or head having a torque-applying gripping surface, and at least one trigger. The head is adjustably or movably mounted at the handle and is adjustable or movable to impart a clamping force at a drive element received at the gripping surface of the head. The trigger is configured to adjust or move the head relative to the handle to impart the clamping force at the drive element. Responsive to a user actuating the trigger, the trigger adjusts or moves the head relative to the handle to impart the clamping force at the drive element irrespective of any movement of the handle relative to the drive element.
