A locking thread insert is wound from wire which is drawn to a generally diamond-shaped cross-section. The wound wire is coiled to a predetermined diameter preferably slightly larger than the diameter of a threaded hole in a female member in which the insert is to be disposed. The threaded screw is free-running in the insert until a predetermined magnitude of loading is encountered at which time a locking and anti-vibration interaction occurs between the crest of the male thread on the screw and the insert. The crest of the male thread is radially compressed when moved axially and circumferentially so as to positively resist loosening under vibration. The interaction between the insert and screw also positively seats and locks the insert in the female member.
