This invention is directed to a self-locking machine screw which includes a recess in the body of the machine screw extending from the end of the machine screw and interrupting the outer surface as slots. The slots join the recess. A resilient locking member having threaded fingers is inserted into the recess with the fingers in the slots. The locking member extends outward from the machine screw thread surfaces so that the threaded fingers must be deflected when the machine screw is screwed into a threaded opening in machine structure to lock the machine screw in position.
