Set of 100 Ice Racing Screws by Kold Kutter
 
These top-quality ice racing screws will give your tires incredible bite on hardpack snow and ice. They also work for extra traction on dirt surfaces, but this will dull the screw heads.

Recommended for use on Hostile MX / MXT tires and BRP Knobby Tyres

Note: Be careful when using this product, as there is risk of a screw coming loose from the tire and flying through the air at a high rate of speed.
