Magnum Radio Thumb screws

[9C1Driver]

I just ordered some Magnum radio thumb screws. I know they are smaller then the normal 6mm size so when I saw some for sale on E-Bay I bought them.

Well the dude sent me eight 6mm thumb screws that are way too big for my 257, Delta, and Omega Force radio's. Off hand does anyone know the correct size? Are they 4mm or 5mm?

I am sure that the "S" series are also the same smaller size as well. Can anyone confirm this for me.

Thanks

I just picked up a S380, I have both 4 and 5mm screws. I will dig them out and see tomorrow.
