rounded bolt head removal

[Maxhead]

HELP!!!

I need to remove a bolt which now has a rounded head...The sucker just won't budge.

There is a mobile bolt removal bloke which can do it at $$$ but I think there might be a tool which I can purchase.

Its a size 12 bolt head and there is bugger all room on one side. A standard socket just goes on so the tool would have to be small.

Any ideas??

Easy out? Drill the hole in the head and use the tool..

There is no way I could get a drill bit in the right place let alone a drill..LOL

There is no room at all. I can get a socket and a spanner in there thats about it....I'll take a photo

As Kallen said Kris. Easy Out is the way to go. being a size 12 bolt you have heaps of room to put a decent easy out in there and simply undo it.

a set like this might cost you $30 but you have it for keeps

that will do it for sure Kris, a decent Alltools or alike will sell those individually no trouble at all.

Any good workshop should be able to lend you a stud remover, it's a self gripping tool, I have one if you want to borrow it, but the plane fare would kill it LOL.
Cheers, the ferret.

EDIT, just re read your post, no room eh.
You could try a smaller socket and belt it on, this would also help loosen the bolt.

Bugger, I found the only shop which stocks these things in Canberra and guess what!!! Its a set of 5 10,11,13,14,15 NO BLOODY 12!!!!


Bwahahha, time for a beer now...Work's done for now. Time to think about it over a beer

If all else fails sacrifice a cheap socket and weld it on.
Or there is that tool like a one size fits all the harder you pull the harder it tightens,
got one here somewhere I'll try put up a pic.

Or try plumbers footprints

[jack]

Hit it with the arc welder (If safe to do so), amazing how that can loosen them up. As the bolt is stuffed it won't do any more harm to it, then try a smaller socket or buy the tool you found on Google.

[Alitis007]

What bot and where is Kris?? A pic will help with suggestions.

[Maxhead]

Haha, you blokes haven't seen me with a welder then, have ya!!! lol

The bolt is the bottom bolt of the EGR system. I was trying to take the block out and stuffed it. There is fuel lines which I had to disconnect everywhere and welding might not be a good idea...lol
I suppose my last resort would be to cover everything up and give it a go.

The socket weld to the bolt might do the trick tho...


If you see a new GU8 exploding in Canberra on the news, you'll know which option I went for :)

[threedogs]

If your welding is chook shite shouldn't pose a problem the heat going down
the bolt may loosen it, have you given it a tap in anger to shock it?????

[BigRAWesty]

Can you cut a slot in the head with a 5" the hold it with a screw driver?

Yeah, I have belted it with a hammer and a fathead screwdriver trying to loosen it but no go. I've had wd40 and freeze spray on it too.

I've just ordered a set of twist sockets (easy out sockets) from eBay....fingers crossed its ganna do the job...lol

not a bad idea either, woll see how these sockets go Thanks

[threedogs]

Cant find the K-Tel spanner but heres some tools which may help

[nissannewby]

Did you use a standard multihex (12 point) socket? Or a single hex (6 point)? If you used the first one then possibly the use of a single hex type will work. I for one use single hex wherever I can as it far reduces the outcome you have.
Also it might be hot but spray some wd40 on it and take it for a hard drive then have a go.

[mudnut]

If you have a big enough mild steel bolt handy, cut the hex head off, drill a its center out, big enough to fit over your rounded bolt head, then weld it on. Saves wasting a socket. By the sound of what you have posted, the bugger will probably snap off. If that happens, there are flexible extension drilling heads available. Some even have a right angle head, for tight spots.

Yeah Matty that was my downfall, I used the 12 point socket. I am now looking at the 6 point ones as I reckon some of the bolts which are hard to get to would be easily got out with the 6 point...

Live and learn :)

I've had a go at it once before but left it as i could not undo it, so I sprayed wd40 on it and left it for a week. Still no luck :)

What about a manifold stud remover? Most tool shops sell them!

[BillsGU]

Go to a good tool supplier and buy a metrinch socket. They are designed to grip in the middle of a bolt head (or nut). I have had a set for many years and have removed mate's rounded bolts on a number of occasions, and you can just buy one - or a complete set.

[taslucas]

Got any pics of that Bill? Ive never heard of one, sounds interesting

[Alitis007]

Worst case would be to try and break the head off the bolt and remove the EGR then attack the stud with wd40 and freeze and release the try to unscrew it with some vice grips? Not sure how much room you've there mate.

Masters and Blackwoods sell them.

No pics at the moment. They are readily available. You only need half the amount of spanners and sockets as one device fits both metric and imperial (and witworth and any other odd size you can come up with), hence the name METRINCH. A pic won't show much. They are designed so that when they apply force to a nut or bolt - they act on the centre of the hexagon instead of the sides. So it does not matter if they are rounded off, they can still apply a force at an angle of the bolt face.

I bought mine at All Tools years ago.
