A self-securing fastener may include a shaft, a shank may be disposed at a head end of the shaft may have a primary side substantially parallel to an axis of rotation of the shaft and a plurality of secondary sides arranged about the axis of rotation, the primary side and the secondary sides may describe a pattern when viewed from a direction substantially normal to the axis of rotation, an external thread may be disposed substantially helically at a tail end of the shaft distal from the head end, and an appendage may be disposed fixedly to the primary side and extending substantially radially to the axis of rotation, the appendage may have a thrust face substantially normal to the axis of rotation, wherein the shank is prevented substantially from turning when the appendage is inserted in an aperture may have a shape substantially similar to the pattern, the thrust face abuts substantially an edge of the aperture, and a nut may have an internal thread substantially complementary to the external thread is rotated along the shaft.
