That'll work on a bolt that isn't recessed, like the diff plug.
Tapping a 6 sided 24mm onto the damaged head, after filing off the burrs, is an option.
Cornwell, Snap-on, Mac... Take your pick. They all offer Bolt extractors for 24mm. I only use welding on anything with bearings as a last resort. Ground issues have caused welded bearings in the past.
$22 for a tool, or $$$ for a repaired housing or replacement axle. Hmmm... decisions, decisions
You have to stand for something, or you'll fall for anything.
