Campers,
I can't answer why, for them.
If you over-tighten the bolts in a glider, plate assemblies may become cracked or damaged,
or the tubing may be crushed (ovalized). An "oval" tube is much weaker than it should be.
Here is what is needed, in the WIKI. You just need to order the right bolt sizes,
from an aircraft supply house.

Hope this will help to answer your question.
Please be careful when tightening the nuts on the nose plates of any glider!!!
MOST gliders have slotted nose plates so that the leading edges can flex without stressing those bolts or related hardware. Many are intentionally left loose enough to allow flexability in the nose area. Over tightening those bolts can lead to serious problems.
Please check with your dealer or manufacturer BEFORE making any adjustments or repairs you're not sure about.

I have tightened noseplate bolts on every glider I've owned. Not much, hopefully not TOO much. I hate it when I can't see ANY thread on the bolt beyond the locknut. Makes me nervous. I was never aware of what you've told us, Fletcher. I wish the manuals said something about that! Why don't they use very-slightly-longer bolts so that we can feel assured by the presence of a little bolt-threading past the nut?
Cheers,
