ABSTRACT:
A socket wrench has a body with a handle, and a head with a hollow cavity. A ratchet mechanism is received in the cavity and has a drive shank for connection with a socket. The ratchet mechanism is pivotally connected to the head in order to allow the head to pivot relative to the ratchet mechanism in an arc along a limited path of travel. The pivotal connection between the head and the ratchet mechanism enables an impact force to be presented to the socket when desired. Optionally, a releasable lock member is provided to prevent relative movement of the head and the ratchet mechanism so that the socket wrench can be used in a manner similar to a conventional ratchet wrench.
