Hi DocNik,
The screw which goes in the Ball mount is the same as in the armature tablet,
which is an M6 with a lenght of 20mm. The screw for the ballmount should have at least
around 45mm in lenght. You need to saw the screwhead off and turn it completely in the Ball mount fixed with locktide... done! Just need to swap it with the original screw by tighten it firmly by hand.
Cheers,
Smaug
