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 Midrange Bolt Pack has everything you need for midrange to high end water-cooled systems. It is for builds with up to two 360mm or 420mm radiators, and everything below. It has bolts for mounting radiators, fans and other components including pumps and reservoirs. It also includes bolts for different radiator configurations including push, pull and push/pull.
