ABSTRACT:
A chuck for use with a manual or powered driver having a drive shaft is provided. A generally cylindrical body member has a tail section and a nose section extending axially forward of a nut. The tail section is adapted to mate with the drive shaft of the driver to rotate therewith, and the nose section has an axial bore formed therein. A plurality of angularly disposed passageways are formed through the nose section and intersect the nose section axial bore. A plurality of jaws are positioned in the angularly disposed passageways, each jaw having a jaw face formed on one side thereof and threads formed on the opposite side thereof. The nut is rotatably mounted relative to the body member and has threads engaging the threads on the jaws. A generally cylindrical sleeve member is in operative communication with the nut so that the sleeve member rotationally drives the nut and so that force in the axial direction toward the nose section is transferred from the nut to the sleeve member. The sleeve member is in operative communication with the tail section to prevent axial movement of the sleeve member and the nut forward of the nose section.
