Abstract

Chuck for use with a manual or powered driver including a nut rotatably mounted on the chuck body and in engagement with the threads of the chuck jaws. The chuck includes a self-contained anti-friction bearing assembly disposed between the nut and a thrust ring, as well as a generally cylindrical front sleeve member in driving engagement with the nut and overlying a nose section of the body of the chuck so that when the front sleeve member is rotated with respect to the body member, the jaws will be moved thereby. The chuck also includes a rust resistant decorative nosepiece as well as an improved nut retainer member.
