The bolt was stripped at the end trying to get the nut off. The nut was totally stripped out. The nut was not cross threaded as stated by ******** blu. They turned on with our fingers . The front end alignment shop stripped it. The only time I ever had this problem . But its the only time I ever used these bolts . But this fucken guy knows it all even when he don't.
