Capello tap

[jam]

Hi
I have a Capello mono ceramic disc kitchen tap ,i have removed the little caps so that i can fit in an allen key to remove the cover of the tap so that i can put on silicon grease because its gone a bit stiff,but cant get any allen size key to fit ,had a closer look and it seems that this type of screwhead is round.Is there some type of tool for this?

Thanks.

A round screwdriver?
Is it torx type - like a 6 pointed star?

Cant really see the star shape but i"ll give it a try with the Torx.
Thanks
