Long ago I stopped using bolts to mount my rotators to the tower. I loctite
a stud in, then use a jam nut after that. This also makes it easier to
align with the holes in the rotator plate. Then I also use a jam nut below
the nut below the plate. Have had no problems since I started doing this
some 20 years ago. Even if the nuts came off, the rotator can't move.
