Abstract
A socket (10) for torquing nuts and bolt heads includes adjustable jaws (18) biased in an outward radial direction by associated helical springs (22) whose inner ends are engaged with a seat preferably embodied by a ball (20). A support member (16) includes slideways (30) that mount slides (24) of the jaws (18) for inward and outward adjusting movement, and each jaw (18) has an inwardly facing engagement surface inclined with a slight inward inclination in an axial direction away from the slide thereof so as to accommodate for clearance between the slide and the associated slideway by jaw tilting that permits gripping of a nut or bolt head with surface-to-surface contact. A camming surface (36) on each jaw is engaged by a camming surface (44) on a sleeve (38) of the socket and defines an angle greater than 90.degree. with the path of jaw movement so as to facilitate jaw adjustment and prevent any binding of the jaws during such adjustment.
