SELF-LOCKING FASTENERS

摘要

A self-locking screw having an elongated beam extending transversely of the screw at one end of the screw. The beam is formed from the material of the screw and has a length less than the diameter of the screw. A distal end of the beam is adapted to engage the axial wall of a generally cylindrical opening to lock the screw in place. A removal tool is also provided to remove the screw. The tool engages in a tool-engaging well in the screw and deflects the beam radially inwards to disengage the beam from the wall of the opening.
