Abstract
An electric screwdriver with automatic screw feeding includes a shaft defining a bit; a body portion, the body portion defining a screw conduit configured to receive the bit; a screw feeder tube; a vacuum coupler, and a screw holding assembly. At least a distal portion of the screw feeder tube between a middle region and distal end may be oriented such that a screw can pass therethrough under a force of gravity. The vacuum coupler may be coupled to the middle region of the screw feeder tube, and may be configured to couple to a vacuum generator. The screw holding assembly may be adjacent the screw conduit and may be configured to receive and hold a screw in a position for engagement by the bit.
