Hi peeps
ive got a bit of a problem in the shape of a sheared head bolt

any ideas ppl, tried mole grips & a pipe wrench so far

Nath

 

you could get a hammer and flat head and hit the edge and it should turn ant clock wise if not use a angel grinder and cut a grove in the midil of the stud and turn it with a flat head screwdriver or hit it once in the grove

 

dont really fancy putting a hammer near the block face

 

If your careful, using a hacksaw cut a screw driver slot in the top, and use a decent large head screwdriver with a socket body (the ones where you can use a spanner on it).

The apply loads of downward pressure by leaning on the screwdriver head and with the spanner on the screwdriver body turn the screwdriver.
Would be an idea to spary some wd40 or similar on it first ensuring it seeps down any minute gap around the bolt.

Plus, to be safe, get a scrap piece of sheet aluminium (small piece) and drill a hole the same size as the top of the bolt. then place this over the bolt head and should you slip off with the screwdriver you'll hit the sheet metal and not the block.

spot on advice m8 that should sort it

 

will have to wait til next weekend now, hopefully it'll come out

cheers ppl

 

or geta set of the draper roller bearing stud extractors, no damage to the head and they do just grip and the harder u turn, the harder they grip, they are about 20 quid for th set from most motorfactor or tool places.

 

Let us know how you get on...

There are some other methods if none of these work...

 

if you can run to it snapon do external extractors about 25 quid each .they come in all the diffrent sizes the part number you need is bexw and the bolt head size .ie bexw 15 and so on .they fit over the outside of the bolt and are taperd so the more force you put on it the better it grips .saved me loads of time and money.

 

May sound a bit savage but could u just not spot weld a nut 2 the top of it???
Im a roofer and not very mechanicly minded so sorry if thats not what should b done near the head

 

These work, they've saved me a few times

 

Ive done this works everytime

 

when it happened to me i welded a nut on ( cover the rest of the block with something splatter cant burn throught thick cardboard should do) had been blasting it with anti seeze oil for a while before hand too.
once you get it moving undo then do up a tiny bit spray some anti seeze in and carry on like this , job done mate, dont be to heavy handed or your in the shit, take your time.
as for extractors, being a engineer these do work but if they snap 9 and a lot do your fucked if you can get the bit out.
look at it this way, it you could undo it when it was soild how much chance do you stand with a extractor? not to say it wont work, i just would waste my time with them, not on a head bolt

 

forgeting my T's al the time should be cant and couldn't doh

 

cheers for the advice ppl

ive decided to take the easy option, my mates uncle is a mechanic, hes gonna sort it for me. should've done it in the first place would've saved me abit in tools
