ABSTRACT:
A ratchet wrench includes an expandible fastener engaging socket which may be positioned over a conventional fastener and which may then be decreased in diameter to effect a gripping attachment. A locking lever is attached to the ratchet wrench and is usable to both decrease the diameter of the expandable socket and to lock the socket in attachment with the fastener. The lever operates in the manner of a conventional lockable plier so as to provide the ratchet socket wrench with a plier-like function.
