Powerspec G460 Wifi antennas loose

I've had my system a couple years now, and the problem has been there since day one, but taking the system across state to repair what is probably an easy fix hasn't felt justified. Is there something I can do to tighten the nuts on the antenna screw points? Is this a known issue with the Asrock z370 motherboard?

I did that, but part of the problem is when I screw the antennas back in, they get loose again.
Is this happening with both antennas / ports?
It is now, yes.
@RidleytheRed just chiming in. Have the antennas always been lose for the couple of years you've had the powerspec? Normally the antenna almost tighten like a coaxial cable wire to back of a modem or tv in a way. If they are not tightening then it could be an issue with the antenna and may need new ones. We'd like to look up your order and create a ticket for this. Can you give us the Powerspec G460XXXXXX serial number?
