ABSTRACT:
A directional backing plate and threaded nut for securing the traction device relative to a flexible rotatable track. The backing plate and nut define noncircular curvilinear peripheries defined by a major axis and a minor axis, wherein the major axis is greater than the minor axis. The backing plate and threaded nut cooperatively engage the stud relative to the track, such that the major axis is substantially perpendicular to the direction of rotation of the track, and the minor axis is substantially parallel to the direction of rotation.
