I can confirm that this is definitely a 5.5mm hex on my 2004 WJ GC passenger and driver side grab bars. I will also add that a standard "deep drive" socket will fit in without any force whatsoever. See photo below....
I tried the two socket-drivers I had, but they were both 6mm or 1/4", and kept spinning on the bolt heads. I finally found a Duralast 5.5mm deep socket at AutoZone for $3.99. It fit like a charm and I pulled the A pillar grab handle covers off in a few seconds.
So glad I found this thread!!
