Track Spikes w/ Thread-Resin. Will Not Fall Out!!! 1/4" Pyramid Style (20 Pack) Aerospace thread resin will 'lock' spikes into track shoes! Spikes are already painted with resin. No application needed! This resin is dry to the touch and will fill in voids between threads when installed. Spikes may be removed and re-installed up to three times. Hex-base makes it the easiest spike to install and remove.
