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.

A traction assembly for a continuous flexible rotating track, the track having an inner surface, and an outer surface for contacting a support surface, the traction assembly comprising: (a) a shaft having a first end and a second end; (b) a substantially noncircular first plate at the first end of the sheet, the first plate having a surface for contacting the inner surface of the track, the surface defined by a first dimension and a second longer dimension perpendicular to the first dimension; and (c) a securing plate contacting the shaft, the securing plate and the first plate adapted to contact a portion of the track therebetween, wherein the first plate is aligned with the direction of track rotation such that the second longer dimension is perpendicular to the direction of track rotation for reducing stress on the inner surface of the track as the track rotates.
