ABSTRACT:
A hook screw driver includes a main body including at least one compartment defined therein. A disc is slidably, removably received in the compartment. The disc has a retaining section with a pattern formed thereon, the pattern being constructed by a number of spaced blocks that constitute a plurality of grooves adapted to securely retain a hook portion of a hook screw. The retaining section of the disc is movable between a first position outside the main body for receiving the hook portion of the hook screw and a second position in the compartment of the main body for retaining the hook portion of the hook screw in position.
