A fastener guide includes a shaft having a first end for transferring torque to a fastener and a second end for receiving a torque from an external source, the shaft including a threaded portion and an axial groove extending axially along the threaded portion. The fastener guide also includes a sleeve slidable axially with respect to the shaft, the sleeve having a first end proximate the first end of the shaft and a second end proximate the second end of the shaft, and a depth-adjustment ring having a threaded inner surface for engaging the threaded portion of the sleeve and a detent ring for selectively engaging the axial groove. |
