I'm glad you took action and did something. However don't you think that drilling the head off of the bolt and then using a punch or something to hammer on the bolt shaft might have loosened the wedge and saved the stem to be used again?

Or where the threads already stripped in the wedge and the shaft moving in it?

Oh well, just make sure to get it sent to a scrap yard or somewhere it will be recycled. If you just trash it, it'll be in a landfill for the foreseeable centuries.
