Caroline,
I entirely agree with you. These used to be precision turned screws with flat heads that seated into the posts precisely. The adjustment was done by either gently reaming the flat inside the post (typically just 1 or 2 mils) to tighten the joint or using a taper reamer to increase the depth of the conical recess in the rod to loosen. Most high quality saxophones and some (preferred by me) high quality clarinets still use this method.
For the ones where you just 'snug it down', I have used thread locking compound labeled temporary or "light", i.e. NOT permanent, to create a slight binding in the threads that acts as a cheap lock...not as good as a tightened fit, but better than a piece of plastic.
I remember that H.N. White (the venerable american manufacturer that made the King saxophones and clarinets...including the famous Super 20) used a variable position headless screw with a locking nut on it. It worked very well and these instruments were a joy to fine tune...no reaming, but when you were done, it was for a long time perfect.
