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.

A wrenching apparatus for fasteners comprising:
- wrenching means for applying a torque to a fastener about a first predetermined axis extending perpendicular to the longitudinal axis of said wrenching means,
- socket means associated with said wrenching means, said socket means and said wrenching means being rotatable about said predetermined axis, said socket means having radially adjustable gripping means for fitting fasteners of differing size,
- collet means operatively positionable between said wrenching means and said socket means and slidable with respect to said socket means along said predetermined axis for causing radial adjustment of said socket means, and
