The sides that fit the bolt head don't start to create the corner until a ways from the radius of the wrench. Grind the wrench and it will be able to grab the part of the bolt down at the bottom of the head,where it still has the flats meeting properly instead of the part where the bolt looks rounded.
I dont know if its clear in the picture, but the head of the bolt is tapered, you can never get the wrench all the way to the flange of the head, it always slip onto the rounded part of the head, and easily strips it even further. Considering that this bolt is bound to be oily, it only makes things even worse. I was having a bit of trouble with it during my last oil change, I thought I had stripped it.
For my next oil change, I bought an allen socket bolt, should make things way easier.
