Why not use a V groove, make the end of the fixing screws in a slightly different angle and so it will be forced downward unto the tube and there is no danger that anything will lift up.

Its funny you should say that, I had the same recommendation made to me by a close mate, but by the time I could alter the drawings the work was already done. So I am stuck with this.
The top of the pier will be tapped for M8 grub screws that have teeth at the end, not sure what they called but I manged to source some from universal fasteners. They should dig in nicely and be out of sight. So that is the compromise
I would assume that it would take quite a bit of force to try and rotate the top with all three nuts tightened.
