Oil Filter Housing Gasket Stripped Bolt

A friend and I were going to change out the OFHG on his 2011 N51. The left lower bolt to the right of the mickey mouse flange ended up stripping after he decided to use an 8mm box wrench. He didn't want to take out the flange and ended up stripping the E10 bolt. Big regret as I told him to use an E10. The shortcut failed. Currently, he has sanded down the head to almost just the bolt shaft. When I tried to use an E10 in hopes of turning it loose, it seemed too tight. Here are the pictures of the bolt head and end of the thread. The first picture is the head. Looks like a battery. Can we use an extractor to drill it in and extract the bolt or take it to a shop? I'm just annoyed he took the shortcut route.

I suggest you pay someone who knows what he is doing to weld a nut on the remaining shaft and unscrew it that way.

you can also try an extractor that grips the outside of the shaft...not the inside, but they don't work all that well.

welding a nut is the way to go.
