The amount of work I put into making it I think it will stay but thanks for your input.

For circular sections the moment of inertia is proportinal to the diameter to the 4th power. If my arithemetic is correct you have reduced the stiffness of the pier by about 6000x by using 10mm bolt(s) instead of the full diameter of the pier (150mm and say 4mm wall).....hence my comment.
I use a 10” steel pier with 1/2”walls. doesn’t move much
