Screw drivers are used to remove or place prosthetic screws. The tips of the screw drivers come in various shapes such as torx, slot, hex, square, quads, and lobes. The shafts come in different lengths and are engaged into a torque wrench or thumb knob.

Note* One Inch and Half Inch Lengths describe the total length of the driver from top to bottom, not shaft length
