need metal-to-wood glue advice (or other ideas)

[Kali]

bought a cheaply made "wood" office chair. the "wood" is some kind of pine laminate. it is held together by bolts that screw into these little metal inserts that themselves screw into the wood. one arm keeps coming loose and when I go to tighten the bolts, they just back the little inserts out. I tried liquid nails household glue (because the kid I sent to the hardware store didn't get the regular liquid nails I had wanted) but it came loose right away. is there some other product that will bind to the metal well and also kind of seep into the wood grain rather than just stick to the surface? anything just surface-sticking comes right off as the wood is so light and cheap.

I have JB Weld in the house, but I don't think it is good for wood, is it? Anybody try gorilla glue? Should I stay with the original plan to use liquid nails? Other ideas for getting this thing to stay put?

here are some pix:
