I do hope you get lucky and you find you can expose enough of the
threaded portion. Judging from the 4-40 setscrew in your photo, I'd
guess that the thread on the broken part (If it's US made) is likely to
be 6-32,


A banana jack from my goodie box measures as follows:

Stud: 3.82 mm (.151") over threads, 0.8mm pitch. Could be a
Chinese 8-32; an 8-32 nut fits but it's a bit sloppy. Std 8-32 is
..157 min OD. M4 x 0.8 isn't a standard metric thread, but who
knows?

Barrel: 5.70 mm (.224") over threads, 0.75mm pitch. M6 x .75 is a
standard metric fine thread.
