ABSTRACT:
A one-piece, lightweight snowmobile fastener for securing a snowmobile stud to a resilient snowmobile track and distributing the cyclical forces on the stud over an extended region on both sides of the track, with the fastener including a collar having a central bore having a female thread for lockingly engaging a male thread on a snowmobile stud with the fastener including a flange having an annular track-engaging face for engaging one surface of a resilient snowmobile track with the flange attached to the collar by a radiused shoulder to permit tear-free engagement of the fastener with a snowmobile track, and an annular reinforcing shoulder integrally connected to the collar to prevent pinching of the track when a force is applied to the end of a snowmobile stud extending through the snowmobile track and the collar in the fastener. The invention also includes a snowmobile power stud that can generate greater traction with a laterally extending blade and still be used with the snowmobile fastener.
