[Harp-L] Does anyone know the size (specs) of the set screw retaining the cable in a shure green bullet?

Hi folks!
Does anyone know the specs for the set screw which is used to secure the mic cable on a Shure D520 (Mexico)?

I have one that was damaged in a drop and it's feel bugs the heck out of my when I'm playing.

Any help identifying the proper replacement would be appreciated.
