  • Patent number: 8689433
    Abstract: An electric screwdriver is coupled to an automatic screw feeding adaptor defining a screw path having a proximal end, a middle region and a distal end. A first screw is received within the screw feeding adaptor and held at a driving position near the distal end of the screw path by applying a distal partial vacuum within the screw feeding adaptor. The first screw is driven, and a torque applied to the first screw is detected. The torque is compared to a minimum torque threshold, and a second screw is moved along the screw path based at least in part upon the comparison.
