Re: Advice on removing snapped s/s bolts from alu block

I've had this exact problem. I've tried most of the solutions posted here, including an oxy-mapp torch.

The thing that worked in the end: an arc welder.

There's corrosion between the bolt and the surrounding aluminum. It's frozen in place.

The current from the welder broke it free in under a second.

Take it to a shop with a welder. Ask them to pull the bolt.
