I assume if it is a solid material, then the standing nubs are for using a spanner bar across them and turning. I haven’t seen this specific one before. Sometimes they are depressions and you have a pin spanner wrench.
Wrench on one nub, or across two like a bar? Could be they have a tool that engages all 4 nubs at once so they don’t snap off, or thing was over tightened.

It’s solid but not very strong. I tried to use a small wrench and it was breaking the nubs. The thing is incredibly tight
