ABSTRACT:
A driver for fasteners, and particularly, a power screwdriver is described which is adapted to drive screws having different diameters. The power screwdriver has a removable guide tube and complementary drive shaft. The guide tube is sized to the diameter of one size of screw. The complementary removable drive shaft is sized to be guided in the guide shaft, reciprocally movable therein to engage and guide a screw located in the guide tube. By removal of one pair of guide tube and complementary drive shaft and replacement with another pair of guide tube and complementary drive shaft adapted for use with screws having a different head diameter, the driver is adapted for driving screws of different head diameters.
