its appears the op doesnt know whats going on here. Your only choice to remove stripped threads is to drill it out. However if you have rounded head then you have more options such as irwin extractors.

I tightened the rest of the bolts back up right away.

Successfully removed wth one of these in about 2 minutes. $5.99

Maybe I'm missing something here, but I'm just an average size/strenght guy, and I have removed three 603 heads with just my 1/2" drive Craftsman ratchet, ... one of them in a junkyard.

Are they supposed to be tougher than that or are the cast-iron heads what's being discussed here?

remove the head of the bolt by drilling out the center to a wide enough radius.

the head will come off and it will remain as a post in the block.

it will then be easier to remove since there is no clamping action along the bolt's length - the majority of the friction has been removed.

The iron head diesels are what I am talking of. 616 617.

This cheater is applied to an 18" breaker bar, which I have had for at least 30 years!

No sense straining myself. I use it on lug nuts too, so I don't have to pull so hard.

This was a last resort for me, not needed.

Had my trusty old Craftsman breaker bar + 2' floor jack handle (not needed)

Suspect PO / mechanic f'd up the splines as the m10 went in straight and

deep - NO gunk in splined bottom.

Had the same issue, and as wal says, it was because I didnt clean out the oil from my first head bolt. Rounded that sucka nasty.

Borrowed an extraction set, Craftsman, from a buddy. It goes on reverse twist, so when you try and loosen , it digs into the head hard. Worked like a charm.

When exactly have you had a charm actually "work"? So in effect, what you're saying is that you hoped it'd work, but never saw any quantifiable result?

;~)

Congrats,

Remarkably, the extractor I used went in about 1/4" and that includes the

chamfer on the extractor.

I was a machinist for 10 years, then rebuild machines, now I only have a

lathe and mill at home.

Makes it easy to make parts, + friend owns steel yard.

Well, and a mig, plasma, ac/dc welder for toys.

The real problem was only distance from home!

You also need to be very careful about keeping it straight while you are applying torque.
I completely agree with both of these points; also, DO NOT USE CHEAP TOOLS. I have pretty good quality tools and I've aready put an uncomfortable amount of wear on one or two of the hex's.

I ensured the bottoms of the broached area was clean AND bit was in line AND

used a quality bit. Even though the bit looks good, I might not use it again.

I know how to make gears, machine splines, and broach parts.

I used to make parts from USA-1 monster truck axles to valves for the Space Shuttle.

Well, it sounds like the PO did the damage. Sorry it came to a head for you.
