The EK Supremacy EVO PreciseMount is an universal mounting mechanism that offers error-preventing, tool-less installation for perfect overclocking performance. Compatible only with the Supremacy waterblocks, EK have integrated lock-off points to prevent over-tightening of the thumb screws. The kit includes threaded studs, springs as well as washers that you'll need to place under the pins to achieve the correct height for the waterblock and prevent any undue pressure on the exposed core.
