A self-locking fastening arrangement includes a member having a substantially planar surface intersected by a blind threaded bore adapted to receive a complimentary threaded bolt or shank. The tapped bore terminates a predetermined distance from the planar surface in a closed end. A resilient substantially cylindrical insert is disposed within the bore adjacent the closed end and is configured to establish a space between the insert and the closed end of the tapped bore. The insert is compressed upon insertion of a threaded shank into the bore a predetermined distance so as to effect self-locking axial loading between the interengaging male and female threads. An annular lip is formed adjacent at least one end of the insert for engaging the tapped bore to prevent inadvertent release of the insert from the bore. In one embodiment, the fastening member takes the form of a self-locking acorn or cap nut having a blind taped bore which receives the resilient insert.
