but it was a Unitorque nut whose inner has no nylon insert but is slightly elliptical so when torqued up grips the thread quite securely....?[/QUOTE]
This is something i had also thought about, there are some anti vibration nuts that are used on the railways, they have 2 lateral slots that cut over halfway thro the thread.
This means that the thread form will collapse slightly and grip the bolt/strut when tightened up.

I use the car everyday so they'll get frequent use.
