Review on Dorman 917 503 Hub Mounting Hardware by Dave Hersma

These were fitted to a 2000 Buick Century. Factory specifications state these bolts should be torqued to 96 ft-lbs. 3 different brands of 13mm heads were used and all 3 people rounded the hex head of these bolts to less than 70 feet of force. Needless to say I don't think these are sockets. 13mm seems a little sloppy, but not by much. The factory screws I removed weren't sloppy at all. If they were a little tighter I would have had to smash the socket in with a hammer. I will return them and buy something better.
