8 - 6mm diameter x 12mm length screws for mounting the Universal Pucks to factory built splitboards. Also can be used for mounting your snowboard binding to the Slider Track. In most cases when mounting your snowboard binding to the Slider Track you will use the screws that came with your binding. Always be aware of screw length when mounting your binding. If the screw is too long it will prevent the Slider Track from sliding over the Universal Puck.
