The bolt in my schwinns is not a tight fit either, just tighten it down
good. The clamping action of the fork blades is pretty good. If the
seat has ever twisted on me, I never noticed. 5 degrees may be
possible if the bolt were loose, but I wouldn't ride it that way.
Why would you ever need to adjust anything but the height?
Tightening bolt good puts everything straight. On the other hand if
you have been riding with the bolt loose that could have elongated the
holes or worn the bolt. I dunno, I have 2 schwinns and have never had
any problems, they're strongest and heaviest unicycles I own.
Getting a bigger bolt certainly wouldn't hurt, unless the holes are off.
but then you probably never raise or lower your seat either. Until it
turns into a loaner......
