ABSTRACT:
A chuck for use with a manual or powered driver including a generally cylindrical body having a nose section and a tail section. The tail section defines an axial bore formed therein to mate with the drive shaft of the driver and the nose section defines an axial bore formed therein and a plurality of angularly disposed passageways formed therethrough and intersecting the axial bore. A plurality of jaws is slidably positioned in each passageway and each jaw defines a jaw face formed on one side and threads formed on the opposite side. A nut is disposed about the body for rotational movement with respect to the body and is in driving engagement with the jaw threads. A generally cylindrical front sleeve overlays the nose section of the body. A generally cylindrical nut retainer is disposed about the body and includes a frusto-conical portion.
