Cross-slot screws for mounting fans on radiators. The special UNC thread, from the non-metric unit system, has been specifically designed for radiators from the USA or the United Kingdom. They form an intermediate size between M3 and M4 threads. With a flat, slightly larger head, the screw sits very well and can also cover larger holes that may be present with various fan types. Therefore, they not only serve a structural function but are also visually appealing and look nice after installation. The thread length has been kept intentionally short to prevent damage to the fins from over-tightening during the installation of the fan, cover, or housing with the radiator. Nevertheless, we would like to emphasize checking the length of the screw before installation!

Important: These screws should only be used in combination with a 25 mm fan, as the screws are too long for narrower fans and can damage the radiator. For narrower fans (20 mm), the screw fits again when used with a fan cover.

Compatibility: XSPC, Swiftech, and others.
