A male fastener, female fastener, a wedge, and a space adapted to receive the wedge, which are configured to secure the female fastener to the male fastener, and to prevent unwanted loosening of the female fastener from the male fastener. The male fastener includes a shaft and the female fastener includes an aperture. The male or female fastener includes a plurality of protruding elements that extend outwardly from an external surface of the shaft or the external surface of the aperture. The wedge (which is affixed to the corresponding male or female fastener) is adapted to be inserted into a space located between a set of protruding elements (or into multiple spaces located between multiple protruding elements), which prevents the female fastener from rotating around the shaft in a direction that would loosen the female fastener from the male fastener. |
