Problem with Whammy bar (keeps unscrewing itself)

[RevolutionWasMyName]

Hey guys, I have a stock white Ibanez Jem.

The problem is, the screw that hold the actual BAR to the whammy bar (the black unit where you plug your whammy bar into) that's attached to the bridge keeps getting loose after a few minutes of playing. I tried screwing it back in place, which remedies the problem temporaraly but it gets loose after a while again.

PS: I'm talking about the actual "ARM HOLDER" wobbling along with the arm that its holding inside the bridge cavity.

Thanks.
