This oddity is one of the rare experimental styles based off of the CD 162. It has a six-sided nut with machine threading embedded in the dome, and a hole through the dome. We do not know for sure what these were intended to be used for. There were two others in this experimental "family": the CD 186 and CD 186.1.
