1. A self-locking thread system comprising:
a first threaded member including a first thread; and
a second threaded member including a second thread configured to be threaded with the first thread;
wherein:
the first thread has a first thread axis; and
the first thread includes a locking thread section that is non-circular in a transverse cross-sectional plane perpendicular to the first thread axis;
the locking thread section is oval in the transverse cross-sectional plane perpendicular to the first thread axis;
the first thread has a leading end and an opposing trailing end;
a first pitch diameter of the locking thread section expands outwardly in a direction from the leading end to the trailing end in a first axial cross-sectional plane parallel to the first thread axis;
a second pitch diameter of the locking thread section tapers inwardly in the direction from the leading end to the trailing end in a second axial cross-sectional plane parallel to the first thread axis and perpendicular to the first axial cross-sectional plane; and
the second threaded member is formed of a deformable polymer.
