These are absolutely essential in my opinion - it only takes a moment's inattention for an expensive accident to occur, and the more complex the rig the more important these caps are.
The rod cap features small size and light weight. It fits my M12 threaded rod on the end, thus accessories mounted on the rod will not be removed accidentally.
