Use a plastic 3/8" diam. piece of tubing (hobby or craft shops) and heat up a 1/4" hex nut to "melt-in" an impression of the nut in one or both of the open ends.

This may be an incredibly stupid question, but I don't ask I will never
know. Does the nut stay in the piece of tubing this grabbing onto the shall we call it male nut sticking out of the radio? It sounds to me like it does. What I'm picturing is something that has to grab onto the screw like device sticking out of the radio and turn this. Is this correct or ??
