I just sent the following email to McGard:
I just had 2 of your 'premium' wheel locks break. The outside edge of the lock portion sheared off halfway around the head of the bolt. They are Part @ 27181, size M14x1.5, key code X-##### #####. So now I can't get 2 of my wheels off my car. 1 I might have been ok with. 2 is VERY unacceptable. Needless to say, I'm a bit perturbed, and on my way to a tire shop to see if they can remove them.
Regards,
Scott Cook
I was trying to rotate my tires & they sheared. Grrr.





Simply not worth a dime.
Put on three brand new nuts, cost me $50, first three no problem, last one sheared and broke the key. I installed them by hand with a ratchet wrench, did not over tighten. I am beginning to believe that these nut are indeed garbage.I am now going to have to pay my local Canadian Tire store around $50 (half hour labour) for to have them removed. The store is going to give me anothe set in exchange, but I am a bit wary about putting them on. Dont trust them anymore. I am going to email McGard with a complaint.
