Snowmobile track lug stud

摘要

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.
