extra long bolt extractor?

[marlinspike]

I need a 9cm long (or longer) bolt extractor for an M6 bolt. Anybody have any ideas?

9cm deep? I have a set of extractors made by Irwin that allow the stud to slide through it, and you turn the extractor witha wrench. Pics and part numbers tomorrow from work

No, 9cm long. The bolt broke and it's just over 8cm in the hole before you hit it.

No, 9cm long. The bolt broke and it's just over 8cm in the hole before you hit it.

You could use something like this which is 3/8'' drive, then put an extension on your ratchet.

Hope this helps.

Ok, maybe I'm using the wrong word because you guys aren't understanding what I'm trying to say. I'm talking about an extractor for a broken bolt, not a rounded bolt head.

Alright, so similar to a spiral flute easy-out? Drill a pilot hole then reverse thread a drill bit sort of thing?

Buy an extension like this.

And then find the correct spiral flute bit or a set like this.

The reason I got confused was because you mentioned the size of the bolt head. For a spiral flute extractor it does not matter what size the bolt is/was, you just find the one that fits.

Sorry about the confusion, hope this helps!

Now that *****!

What kind of material is it stuck in????

Hope you say cast iron.....its the easiest to get out, but if your in al-you-mini-um....das-bad.

AND---How hard is the bolt??? If it's a 10 or better....oh boy.

squirt Kroil in it first.

I almost had to deal with situation like yours with a long starter bolt that was cross-threaded. I managed to work it out without busting the bolt. Don't know what I would have done if that bolt broke. Best of luck getting it removed.

 

[marlinspike]

M6 bolt. Yep, it's in aluminum. It's not in there all that tightly, I just need to get something on it. It's not cross-threaded or anything. The bolts are supposedly 8.8, but given how little torque it took to snap it when putting it back in, I have my doubts.

spiral extractors have a square drive on the back you can put a tap socket on(available at searshttp://www.tooltopia.com/lisle-70500.aspx) and then use an extension
beyond that, ive seen some extractors that have long necks

A nice idea, but an M6 bolt hole is pretty small.

 

[kunkernator]

Do you think it is fairly loose (enough to take out with your fingers)? My first thought after I realized how small an M6 was: Take a metal rod/dowel put a little JB Weld/putty on the end, stick it to your bolt and screw out. Hard to say if this would work without seeing it.

Food for thought.

I would go with left handed bit and extension. You can get them pretty small, as small as 1/16".

Nice!! Glad it wasn't too difficult

 

[marlinspike]

Whoa that picture came out big...sorry about that.

And I'm glad too - this is apparently a common problem when changing the water pump on a M62TU BMW engine, and everybody else on the internet ended up removing the timing chain cover (a full day's work even for a master tech in a fully-equipped shop). The shoe goo was just grippy enough to back out the screw (not to glue the pieces together, but just to provide a grippy rubbery surface), and my tiny Stahlwille magnetic pickup tool slid into the M6 hole to pull it out.
