Kaylock Nuts

[Specky]

and some have stiff nuts...

Quite correct - kaylock nuts are required for the yoke to damper socket head bolts and similarly for the front wishbone brace.
These are expensive but I have not been able to find an alternative.
My aero-engineering contacts know these by various names, including jet nuts and as mentioned they are widely used in turbines and very high temperature applications. In automotive they are used as self locking (using the serrated contact face) for high vibration situations.

Thanks for your help

Can you re-use Kaylock nuts? I need to replace the spherical joint on the exhaust, do the nuts come off easily or am I going to need new nuts and studs?
