What the heck is the screw called??

I've searched the internet and scratched my head so much that I barely have any hair left.
What is the name of this screw, where you can insert a cover cap into the screw head???

Rampamuff, but that looks like a homemade setup..

I have the same type of screw in an old bookshelf, definitely not homemade.
Unfortunately, I cannot provide a name.
