ABSTRACT:
A chuck for use with a manual or powered driver having a rotatable drive shaft is provided. A plurality of jaws are slidably positioned in a body member. Each jaw has a jaw face formed on one side and threads formed on the opposite side. Each jaw face includes a first ridge substantially parallel to the chuck axis. The first ridge is offset from, and substantially parallel to, a plane including the jaw axis and the chuck axis. A second ridge is substantially parallel to the first ridge but offset from the plane opposite the first ridge. A third ridge is disposed between the first and second ridges and has a peak on the opposite side from the chuck axis of a plane including the peaks of the first and second ridges.
