That threaded hole is there to allow a bolt to be threaded into the shaft so that there is something to grab onto to pull out the shaft once the internal clip is removed.
A bolt would only be used during maintenance. Other than that the hole is empty.
The shaft is the top part of suspension that the shock attaches to.
