Epoxy or superglue? What's works best to attach a metal bolt sleeve to a chair?

The issue: I have a wooden chair (oak). The bolts that hold the seat and legs in place were screwed into a metal sleeve – the sleeve used to be held in place by small metal prongs on the sleeve. Those prongs came loose.

I want to re-seat the sleeve and the rebolt the seat in place. What is the better adhesive? I want the metal sleeve to stay in place (and be strong) forever.

What should I use?
