Abstract: A screw-in stud has a self-tapping thread on a shank, and a head portion that has a cone shaped protrusion that will extend outwardly from a lug of an off road tire or a snowmobile track in which the screw is threaded. The cone shaped protrusion has a carbide pin at the outer end that is sharpened for increasing traction.

Abstract: A traction point for a snowmobile track includes a fastener that extends through the track with a head on one side of the track, and a pointed nut that has a pointed end and which is threaded onto the fastener on the opposite side of the track from the fastener head. The traction point includes a base for support on the track, and pyramidal shaped reinforcement gussets that merge at a point to provide for increased traction for the snowmobile. Small ribs can be provided on the traction point for engaging the track to reduce the likelihood of the traction point unthreading and coming off during use. The pyramid shaped flanges give a paddle effect as they engage ice or snow to provide increased surface area for reaction of the driving forces from a snowmobile transmitted through the track, and also increased corner traction and braking effect.
