Does anybody know the spec for the rear axle nut? I can’t find it online and need a replacement.

I have a gps mount attached to the bike with a CarPlay screen mounted to it. It seems to wobble a massive amount so I’ve mounted it to the handlebar, much better. It seems like the whole area around the headlight wobbles significantly when in bumpy terrain. I’ve tightened all bolts in the area but it made no difference. Is anyone else having the same issue?
