When building a water-cooled system you will always find the need for extra bolts. The right bolts are very difficult to find and even when you find some that will fit, they are usually quite ugly. I have put together a collection of all of the bolts which are needed for building water-cooled systems. My bolts are mostly custom and designed to have perfect aesthetics, specifically for building water-cooled systems.
The Extreme Bolt Pack has everything you need for even the most extreme system. It is for builds with up to four 480mm or 560mm radiators, and everything below. It has bolts for mounting radiators, fans and other components including pumps and reservoirs. It includes bolts for modding, mounting custom panels etc. It also includes bolts for different radiator configurations including push, pull and push/pull.
