Plastic to metal epoxy?

Hey,

Quick question here, I have a bathroom fan that the plastic impeller has become loose and is now sliding down creating a screeching sound.

I was going to go out an buy a new fan and just change out the motor/impeller and keep the box.

But just before I was going to head out to the store I figured I'd ask if it's possible to find a plastic to metal resin epoxy that would hold the impeller in place keep it from sliding down.

I'd rather spend 5-10$ epoxy than 50-65$ on a new fan.

Thanks for the answers in advance.
