Abstract
A chuck for use with a power driver having a rotatable drive spindle is provided. The chuck may include a sleeve comprising a sleeve tightening surface that may be configured to engage with a nut tightening surface to tighten a nut when the sleeve is rotated into a tightening position. With the sleeve disposed in a sleeve locked position, a click pawl may be engaged with a click stopping edge of one of the plurality of click teeth to inhibit rotation of the nut in a first rotational direction to loosen the nut. A lock pawl may also be engaged with a lock stopping edge of one of the plurality of lock teeth to inhibit rotation of the sleeve in a second rotational direction due to the inertia in the sleeve that would tend to further tighten the nut.
