ABSTRACT:
An adjustable socket having a driver rotatably drivable about a central axis, wherein the driver includes inclined slideways extending with both radial and axial components with respect to the central axis. Jaws are supported within corresponding slideways of the driver for movement with respect to the central axis. The jaws each include an internal driver aperture having an axis transverse to the central axis. An adjuster provided with the socket includes a jaw operating member, jaw clips and a connection that secures the jaws, jaw operating member and jaw clips, to maintain the socket in the assembled condition and to limit inward movement of the jaws. The jaw operating member includes an annular flange projecting outwardly in a radial direction with respect to the central axis to axially locate the jaw clips. Mating helical surfaces support the adjuster on =the driver for axial adjusting rotation to move the jaws axially and concomitantly inwardly and outwardly in the slideways for size adjustment of the jaws between open and closed positions.
