Heavy piercings? Nah kidding but as said they're meant for controlling the dead bodies aka 6 paths of Pain, end of topic.
NO he used them to transmit his chacra into the 6 pathsthats a sign that he is synchronized with gedo mazo
i like ur answer the bestWhen he summoned the Gedo Mazo statue , he putted those rods in his back in over to control it . Later he figured that he can control the 6 paths of pain by using them , so he stayed that way in order to control them and bcoz he is stronger that way
