I despise big auto companies that cheapen their nuts. The thin wall nuts that came installed on my wife's Ford Fusion looked fine until I replaced the wheel bearing and made the mistake of tightening the eyelets with a 12 point socket. This ripped them apart and even prevented me from applying the specified torque. I was very happy to find an exact replacement at a low price here at Revain rather than buying a whole new 20 piece set. Lesson Learned - Only use a hex socket!
