A screwdriver and mating screw are shown with interlocking features for coupling with one another to facilitate driving the screw into a workpiece. The screwdriver includes a handle and a blade with an engagement flange on the outer extremity of the blade. The engagement flange engages a complementary recess provided in the head of the mating screw, the recess including a downwardly facing shoulder. A coupling sleeve mounted on the blade exerts an axially directed force on the screw once the engagement flange and complementary recess are engaged to thereby interlock the screwdriver and mating screw.
