Abstract
A chuck device for use with a manual or powered driver has a body member with a plurality of angularly disposed passageways formed therethrough. A jaw is slidably positioned in each passageway. Each jaw has a tool engaging face formed on one side and threads formed on the opposite side. The jaws are threadedly engaged with a rotatable nut mounted on the body member. A sleeve member is in rotational engagement with a nut whereby rotation of the sleeve causes the nut to rotate and the jaws to advance or retract within their respective passageways. Each jaw and its respective passageway has a unique matching profile different from the other jaws and respective passageways so that the jaws cannot be interchanged with different passageways in the chuck.
