Ufo set screw size

[timscues]

Does anybody know what size socket or hex fits the street pro or quadzilla,
was going to repack the cans but nothing I have fits?

I saw 3 mm on my Dragstar "bologna-cut" fit the oval-head allen screw. I tried SAE, no-go. You may need some heat on the screw if it has any threadlocker.
