A hook screw driver includes an upper body and a lower body. One of the upper body and the lower body includes a retaining section having a pattern formed thereon. The pattern is constructed by a number of spaced blocks that constitute a plurality of grooves adapted to securely retain a hook portion of a hook screw. An engaging device is provided for disengagably engaging the upper body with the lower body. When the engaging device is in a first position, the upper body and the lower body are retained in a disengaged status such that the upper body and the lower body is rotatable relative to each other to reveal the retaining section for receiving the hook portion of the hook screw. When the engaging device is in a second position, the upper body and the lower body are retained in a closed, non-rotatable relationship to securely hold the hook portion of the hook screw.
