Good for 27 mm fans mounting to radiator
They were the right length to attach my 27 mm fans to my radiator in a push pull configuration through the top rails of my chassis. I appreciate also that they come with convenient little washers that could allow you potentially to adjust the length if they were too long, and to add some width if more contact was needed,. Seems a little bit expensive for what it is, but I got the job done so five stars I will give.

Flexibility for radiator mounting
I'm using these with the Cooler Master MasterLiquid Atmos 240 AIO. The included 30mm screws were only long enough to attach the fans to the radiator. I wanted to attach the radiator to the case with the fans in between (side mount intake), so these 34mm screws gave me the extra length I needed. The screws fit as expected, and the black color matches my case. The price isn't great but is OK for a specialty project, and the Prime next-day delivery really helped me complete my build.

I would look for something else but they are serviceable
Works for corsairs 5000D RS case bottom and shroud fans, however they are slightly longer then the case wants. If used on the bottom it will block the filter.

Great screw pack for radiator heatsinks...
The length I needed to attach Asus TUF 120 ml fans to my radiator.
