ABSTRACT:
A snowmobile stud for attachment to a flexible resilient snowmobile track with the stud having a cylindrical member having a flat stud head of predetermined area on one end with edges to hold the stud head from rotating during assembly, an intermediate threaded section, a conical-like point extending from the cylinder member and a lock nut for holding the stud on a snowmobile track. Located between the lock nut and the resilient flexible track is a cleat which has sufficiently large surface area to prevent it from becoming embedded in the track, the material of the stud is of predetermined hardness so as to sustain the high speed abuse that occurs when racing snowmobiles on ice.
