stud extractor

[Cloggy Saint]

I'm looking to get a stud extractor but don't know which would be the best type as there seem to be many variations. Can someone recommend a good set?

Two nuts are the usual piece of kit.

Depends if the studs are intact, rusted in or broken off

That used to be the way I did it, until I used a stud extractor.

Very handy tool.

Snapped exhaust studs, in ally heads....
Put a nut over the broken stud, weld up the inner of the nut to the top of the broken stud, and then just fit a spanner and unwind...

The heat generated lets the broken stud unwind...

Roller stud extractors are good, but they wont get stuck ones out. For that you need 2 nuts, 2 spanners, and some heat and time. Remember if it takes half an hour to get one stud out intact, that is a good time saving on getting a broken one out.

I use one of these for scrap studs -

You wont be able to reuse them after though which is where two nuts and spanners come into it

A point that I frequently try to impress on my current 'apprentice', but, with the impatience of youth, is often ignored!

I've got the Irwin set and thus far they have taken out every one I've set them on to. I've just bought the additional ones to make up the complete set.

[Cloggy Saint]

I don't have any broken (yet) or stuck studs, I just want the right tool for the job.

That's the ones. Best example was a rounded bolt on a drop link, which had also been attacked with a grinder so the bolt was not only rounded, there was only about 3mm left on it. 6 point socket would grip it but couldn't get enough purchase to turn it. Irwin remover took it off in seconds.

Irwin bolt grip has saved me a lot of swearing alot of time working on old cars.I haven't come across a rusty nut it hasn't removed yet.

Not tried them on broken studs tho.

What about an exhaust stud that has snapped flush with the head?is drilling and helicoil the only way to get it out

So you are looking for an answer to a problem that does not,yet, exist?

Put a nut over the broken stud, (even when it's flush with the head) weld up the inner of the nut to the top of the broken stud, and then just fit a spanner and unwind...

The heat generated lets the broken stud unwind...I have seen this carried out on a Sierra Cosworth Head, with numerous broken studs...very effective.

I agree with the above. If you are just doing your own head just use the 2 nut technique, it should get them all out with some patience.

I think we are a crossed purposes as well with the term "stud extractor". I think the type th OP is talking about is ones for getting intact, good condition studs out. Not "easy outs" or the ones for fooked studs, snapped, or round headed bolts.

IMO you would be better off getting a heat source, like a propane/mapp gas blow lamp, as this WILL loosen stuck studs so they can be removed using the 2 nut method, and is no end of use elsewhere too.
