Anyone ever encounter this before?

There is no tension on the threads so it will come out easily. Use a Dremel with thin cutting disk and cut a small grove in the top the the bolt then use a flat blade screw driver to back it out.

I will certainly try this tomorrow. Sounds like good advice.

A recomendetion I picked up in the forum and worked well for me ( not on an axle bolt), use Irwin cobalt drill bits. They are amazing.
I got the The left spiral with the extraction tool.
Most chances the bit will remove the bolt when you will go one size up.
