cheers all. will check that out Chris.
well well well , the replacement whell nut lock came today , only 3 weeks ......and you guessed it .....it chewed up again. I made sure it was well onto locking nut and slowly applied the pressure to release locking nut and wooopppsssss again it just chewed up the bits inside.
What absalute crap Mcguard stuff is. On line on many forums it said they were and now I can back it up.
Now I need to get them odd with a tool, or try garages once I can get off this snowy mountain side.
Moral of the story......
NEVER BUY MCGUARD LOCKING WHEEL NUTS.....
