I've used this method. Had to tap it into the bolt head, but it came right out.

Yes, and if difficult the left handed drill bit help as well.

sometimes.

I would spray whatever you have with lots of PB blaster or something close and let it sit before I did anymore damage. if the bolt stripped because its a ball of rust inside the head tube its best to free that up as much as possible.

The problem with trying a bolt extractor is that if you break the extractor now you have a piece of hardened steel stuck in the drive recess to contend with. I would suggest pounding a Torx or oversized hex (perhaps fractional) into the opening. I have also had success with epoxying a sacrificial hex driver into the recess; it is much less likely than an EZ-out to break off.

I recently experienced a similar situation. The torque was too high to get any backout bite. I used a Wera Hex-Plus bit for the save and swear by them now.

A persuasive testament to the effectiveness of the hex-plus (TLDW @ 12:10)

Technically speaking if you ask for a hex head bolt this is what you are going to get.
What you are trying to remove is an Allen or socket head bolt

Once you have toe stripped bolt out, you've solved only half of the problem.

Find the allen wrench you were using when it stripped. Throw that sucker away and buy a new one. DO NOT save it somewhere for a spare.

I can attest to the effectiveness of hammering in a torx bit, but I'm definitely gonna check out this hex plus business.

I work on hydraulic stuff like excavators a lot, and they are a total bastard. When I come across a barely-accessible rounded-out allen head, I want hex plus on my side.

Thanks for the tip!
