ABSTRACT:
A power hand tool for driving a fastener a desired depth into a workpiece. The power tool includes a depth adjust sleeve for varying a resulting driving depth of the fastener into the workpiece. A depth indicator is included to allow a user to gauge the resulting driving depth of the fastener into the workpiece based on his adjustment of the depth adjust sleeve. In one embodiment, the depth indicator comprises a marker coupled to the depth adjust sleeve such that its location varies monotonically in response to varying the resulting driving depth, a lens to allow the marker to be clearly seen by the user, and a scale to which the location of the marker is compared. A driving mechanism is then used for driving the fastener into the workpiece until the resulting driving depth is attained.
