locking wheel nuts
i have bought a set of locking w nuts from halfords. cost £32.98
pick up the number from their catalog and thay will get it for you in a week. perfect fit.recommended
Don't know about these but I had the MB original ones and they were shite! Ten minutes after fitting them they were already rusting!... and I broke the head of one of them when trying to undo it.
I had to replace my locking nuts as the last owner chiseled them off after loosing the key. Halfords were the the cheapest then and Mcgard are the MB oem. They are not that difficult to remove in anger merely take a little time.
If you loose the key you have to get a new one from MB as Mcgard wont supply keys for MB nuts even though they make them. And Mgard only seem to supply 4 nuts of the same keying: if you want one for the spare you have problems.
