A traction stud for an endless snowmobile belt including an elongate rod having a ground engagable end and a threaded end which can be coupled to the track with a threaded fastener. A slot is cut into the threaded portion of the track such that the terminal end threaded portion is separated from the remaining threaded portion by a gap but coupled thereto via a reduced stem which, after installation, can be broken away so that the remaining portion of the stud shank is flush with the fastener. The invention also contemplates the method of making the stud and the method of installing the stud with a transverse slot providing a weakened break away portion which can be severed by the application of transverse force to remove the axially inner terminal end of the stud.
