Abstract
A chuck for use with a manual or powered driver having a rotatable drive shaft is provided. The chuck includes a plurality of jaws slidably positioned in angularly disposed passageways in a body member. Each of the jaws has a jaw face formed on one side and threads formed on the other. A nut includes axially aligned threaded sections. Each of the sections is rotatably mounted on the body in engagement with the jaw threads. A generally cylindrical front sleeve member is in driving engagement with the nut whereby the jaws will be moved by the nut when the front sleeve member is rotated with respect to the body. The first section and the second section are rotated with respect to each other when the jaws are in a gripping engagement with a tool shaft.
