Anyone else had this happen? I had one snap when undoing a wheel on Saturday. Also 2 snap on the o/s/f today when doing my brakes at lunch. This isnt really a problem as there is enough stud sticking out to unwind. The bolts are the same as new Micra bolts, so i ordered 12 new ones and a set of Mcgard lock nuts for less than the price of 16 genuine Renault bolts. Just wondered if anyone else has had this?
