So, I've got this awesome old Ibanez Radius and its got one of those flushmount output jacks with no nut on the outside. It's been loose lately and the cable falls out sometimes. So I opened up the back and I see the output jack but its not like my other Ibanez. I don't wanna mess up my wire so does anyone know a tried-and-true method to tighten one of these flushmount output jacks? It looks a bit like this


Thanks in advance
