Do you know what this is? If you've dropped the column on a '59-'61 (and probably others of that era), you do. But why the star-shaped head, and what is the appropriate tool. Back in the Pleistocene era, when I first encountered one of these, I'd just grab it with pliers. Today I was able to tighten the one on my '61 using a 7 mm socket. But it's not a great "bite" and can't be what GM intended.
I used no tool on mine. Just hand tight.
I believe it's a 12 point. A 1/4" socket set should have one that fits. Usually can use the screwdriver shaft, as its not that tight. The paint may have to chip off to get a bite.
I think it was the only screw head they had back then that wasn't as "noticeable"(?).
Fishnjim is correct in that 1/4" 12 point socket will work, but better is a 1/4" 8 point socket.

David,
Yes it is unique.
The literature says it was use to avoid snagging clothing, particularly lady's dresses and stockings.
By the way, they were not painted the same color as the lower steel part of the dash or the cover - repaints they seem to always be painted - no no.
Attached is a close-up of the hardware. - if I can attach it - a bitch-kitty to attach stuff for me anyway.
Have fun,
Steve B.
