Abstract: The present invention provides a traction device that is selectively removable from a threaded aperture and allows for the operative engagement of the traction device into a threaded aperture without requiring the rotation of the traction member relative to the threaded receptacle. The traction device includes a head and a shaft projecting from the head. The head may include any of a variety of ground engaging members such as wedges, spikes or teeth. A plurality of fins extend from the shaft and exhibit substantially equal flex resistance towards the head and away from the head. Upon operable engagement, the fins are biased between successive threads. The traction device may be configured to provide a substantially equal insertion force and extraction force.
