High bar stool screws constantly getting loose

I bought a high table with bar chairs, and it seems every few days after tightening the screws in the chair, they become loose again, and the chair is wobbly/unstable. I've provided some photos of the chair. I have two of them, and it happens with both. Is there a better fix, rather than having to re-tighten the screws every few days?

If the bolts are threaded into a metal insert then I would apply a drop of red (permenant) Loctite or blue (removable) Loctite. Let it sit for a day to allow the thread locker to harden.

You can also slightly squish the threads on the bolt by lightly taping with a hammer. Do not damage the threads on the very end of the bolt as they need to be in good shape to get started. But the slightly dented threads will bind when you screw it in and help prevent loosening.

There are no metal inserts.

I would remove one screw at a time. Smear the threads with 5 minute epoxy. Then put it back and tighten. After doing all the screws let the stool sit overnight before using it.
