Abstract (en)
[origin: WO9846397A1] A screwdriver blade construction has a tip (20). The tip (20) has a vertical wall (42-45) that is parallel to the blade's longitudinal axis and consequently parallel to the face of a screw groove. The opposite wall (32-35) of the tip (20) is tapered or angled to the vertical wall (42-45) to create a taper. When one inserts the tip (20) into a surgical screw, the tip (20) and screw groove create an interference fit. The vertical face is the driving face, and it lies flat against the face of the screw groove that is driven. This prevents cam-out of the tip (20) from the screw.
