Locking nuts

Hi all,

Could anybody recommend a good set of locking wheel nuts? Recently had grief with a set due to the adapter rounding stupidly easily!cf_emoticons__BangHead: Pretty sure they need to be M12 1.5x24 but don't hold me to it 

hi..
im using the mcgard ones from halfords.. £37
just dont over crank them when you tighten them.
hope this helps
