One of the ports on my 8503 S param test set moved, and yes it
was the one with the plastic washers on it. It drove me mad so I simply turned
the washers upside down and tightened the screws carefully.

Arguably a better way is to take a file and remove about 0.2 mm from the thin end of the washers - there's a change of diameter. That will allow the bridge to tighten down, but onto a waster, rather than with a lot of air around it, as you will have. Of course your method is slightly quicker, and reversible.
