Does Sebenza's clip screw softer than others?

I use hex wrench removed the clip and put it back, but the screw has stripped.
So I guess the clip screw sofer than others. because it never happened to other screw.

It looks to me like the clip screw goes directly into the titanium. So yes, that would make the threading on the scales for the screw softer than the others.
