Claim:
An adjustable socket with a number of selectable socket size openings available to accommodate different size fasteners, an exterior drive member having a longitudinal axis, an end of said exterior drive member having a cam surface, a series of serrated teeth and a grooved diameter positioned at said end, an axially moveable inner drive unit positioned within said exterior drive member, said inner drive unit being manually rotatable to different positions corresponding to a selected socket size opening, first and second jaw members movably secured to said interior drive unit whereby said first and second jaw members are movable to fixed lateral jaw positions, each fixed lateral jaw position corresponding to that of a selected socket size during axial rotation of said inner drive unit; a series of serrated teeth positioned at the lower end of said interior driver unit which engage the serrated teeth formed within said exterior driver member said inner drive member being rotatable in a first second mode when simultaneously pulled in a first direction along said longitudinal axis to disengage the serrated teeth of said exterior driver member and said internal drive unit, thereby enabling a user to adjust said first and second jaw members laterally to a selected socket size, said teeth of said interior drive unit and the teeth of the exterior driver member being interlocked to secure the selected socket size during a second mode of operation, said first and second jaw members each having an angled radius relief on its surface which corresponds to an angled surface formed on said exterior driver member allowing for additional lateral expansion of said first and second jaw members as said inner drive member is pulled in said first direction.
