Mounting hardware for 20 mm fans

These M4 button-head screws are made for securing 20 mm thick fans to radiator flanges. The 8 mm thread length engages the radiator without bottoming out, and the black galvanised steel finish resists corrosion in liquid-cooling loops. Builders assembling custom water-cooling radiators will find the hex drive prevents cam-out during installation. They are supplied new and conform to DIN 7380 quality grade.

Compatibility with common radiator brands

The fasteners suit Black Ice, XSPC RS Series, Koolance and D-Tek radiators among others. Each screw has a 7 mm head diameter that distributes clamping force evenly across the fan frame. Because the total length is 10 mm, they clear standard fan mounting holes without protruding into the radiator core. No additional washers or spacers are required for the listed radiators. Builders using other radiator brands should verify flange thickness before fitting.

Low-profile fastening with hex drive

The 7 mm button head sits nearly flush with the fan frame, leaving maximum clearance for tubing or adjacent components. Hex drive allows positive torque control so the galvanised steel threads do not strip the softer radiator brass. In normal operation the screws add negligible thermal mass and produce no audible vibration. Power draw is not applicable for passive fasteners.

Questions about this item

Will the 8 mm thread length reach the bottom of a 20 mm fan frame without poking through the radiator?

The thread is 8 mm long and the overall screw is 10 mm, so it stops well before a 20 mm frame bottoms out on the radiator.

Does the black finish stay intact when the hex head is driven repeatedly during a full-day build?

The galvanized steel body with black coating resists wear from hex-key use during extended assembly sessions.

Which radiator brands have the M4 thread pattern these screws match?

They fit Black Ice, XSPC RS Series, Koolance and D-Tek radiators that use M4 mounting holes.
