Abstract: A device for facilitating driving of a threaded screw into a member by a screw driver having a shank and a drive head. Such device comprises an elongated housing having first and second longitudinally aligned portions, the first portion configured to readily removably receive the shank of the screw driver with a friction fit restraining the shank to limited relative movement with respect to the first portion along the longitudinal axis of the shank, and defining an enlarged longitudinal slot through which the drive head and shank of the screw driver are insertable at an angle to the longitudinal axis of the first portion. A second portion is configured to have one end engageable with such member and receive a threaded screw and drive head in driving relation therein.
