I am a welder and believe me -welding a nut inside cast aluminum rim is not an option. I will not even mention what power surges can do to car electronisc.
Than I had an incident few months ago, when couple of my bolts got them-self overtorqued. I torqued them personally, so I know they have been about 100 in-lb (I think there is 80 recommended for E, but I never remember details and torque all the cars 100).
So the 2 bolts for some reason took over 200 to break loose. I had to use a socket with big lever to do so. Thin'wall socket had some play in the hole and when I applied big force the bolt head extension bend in the process. I think some people in similar situation might not have big wrench and playing with smaller wrenches might fatiqe the bolt in its weakest point and brake it off.
So my conclusion is, that the factory lug wrench is having the big collar on it for a reason. Use it on hard to loose bolts, or get a thick wall socket, that will prevent bolt bending. The best would be Cross-bar wrench.
