The shop once damaged the bolts when trying to remove a wheel on a Mercedes ML63 with a regular socket. The chrome cover came off and the head began to peel off. This was a problem because putting the screw back in would do more damage and replacing it again would cause more headaches. Glad I had a spare screw with me. So I bought this outlet to save myself all the hassle next time. Haven't used it yet but I checked the fit and it's great.
