Abstract
A chuck for use with a manual or powered driver having a rotatable drive shaft, the chuck having a generally cylindrical body member having a nose section and a tail section. A plurality of jaws is slidably positioned in the body, and each jaw has a jaw face formed on one side thereof and threads formed on the opposite side. A nut is rotatably mounted on the body in engagement with the jaw threads so that rotation of the nut moves the jaws axially within the passageways. A tightening indicator having a first ring received operatively between the jaws and the body and a second ring rotationally coupled to and in operative engagement with the sleeve and the first ring. When the tightening indicator is in a first state, the first ring and the second ring are rotationally coupled to each other and the sleeve when the sleeve is rotated in the opening or closing directions, and when the tightening indicator is in a second state, the second ring rotates relative to the first ring in the closing direction but is rotationally fixed to the first ring in the opening direction.
