Removing A Broken Bolt Or Stud With A Bolt Extractor

[BuickDoc]

Bolts do not always break off with a flat or concave surface. Sometimes there is a 'mountain' of metal preventing starting a drill in the center. I have used a Dremel tool with a pointed diamond bit to carefully flatten the 'mountain' and to start the center hole for the bit. I also use left-handed drill bits. Sometimes the action of the drill bit turning counter clockwise will rotate the bolt out. I am an expert at breaking bolts, so listen to me!

Hey that bolt was bran new!That why it came out so find.Try that on a rusty manifold stud.

@abidou1999 The bolt wasn't new, but not dirty or rusty either. I think it was overtightened and snapped. There are other methods, just showing one.

Nice. I have a bolt that I need to do this to. Thanks for posting.

[supersman2000]

thanks for teh vid you just saved me a whole lot of troubble

[bmwnasher]

Those things will not work on a rusty or tight bolt BEWARE if the easy out breaks your in trouble.

[shsmustangs]

thanks for the tip...have a broken bolt in my cylinder head...gonna try this method

[yingyangnike]

@shsmustangs hey did it work on your broken cylinder man?/

Another thing that works if you don't have a screw extractor.. Drill a hole in the center that's about 2/3rds the diameter of the bolt.. Take an Allen key (Hex Key) that's slightly larger than the hole and tap it in with a hammer... Works almost every time and it's easy.

What size mm bolt was that you removed??? becasue I over tightened my clutch to the flywheel and the bolt head snapped off! As my bolt is quite small. Thanks,

@GoogleG11993 This vid was a 6mm.

[dragoon2784]

thank you I have two broken screws in my lawn mower gonna try this

[grenman20]

where do you get a punch like that



[90gtvert]

@grenman20 They aren't too hard to find. Home Depot, Lowes, Harbor Freight, Sears. Search for "spring loaded center punch" or "automatic center punch".

hey i broke off a bolt on my trans pan think this would work?

[90gtvert]

@scottthebarber Possibly. I always try vise grips first if there's anything to clamp onto. LH drill bit is another option. Cutting a notch to use a screwdriver could work. Sometimes chiseling in order to spin counter-clockwise can work if there's anything protruding.

I have a bolt broken off in the position sensor side of the intake camshaft. The guys over at ACE tried a battery powered drill and bolt extractor but somehow managed to break the extractor off in the bolt. :(. So before I take the cam to the machine shop for them to rape my wallet...what do you suggest?

[90gtvert]

@madoggyd Depending how bad it is, a machine shop may be worth the money. I take the nasty ones to a machinist that can drill a lot straighter and more precise than me and it's usually all of about $20-30. A left handed drill bit could be an option, but if you are at all unsure of it don't ruin a cam to save that kind of money at a machine shop.

way better then wilding the bolt , what I was doing is drill the whole bolt off with same thread size or a little bigger then put new bolt and a screw to hold it from the other side but but u dont always have that needed space, well good video I just think it will be a little harder when the bolt is rusted out .

[jkterminator]

will this work for a broken screw as well? i wated to try something like this but was scared i would damage the thread....thing is its only like a small screw

[90gtvert]

@jkterminator Maybe. If it's very small, perhaps try a small left hand drill bit. Run the drill in reverse and perhaps it will grab the remaining screw and spin it out. If there's some of the screw still sticking out, it's usually easiest to use vice grips to clamp on and unscrew it.

Wow, so easy. I've got an engine mount bolt thats sheared off on my Aprilia Mille R. Bolt is 12.9 tensile strength and drilling with a carbide bit is taking for ever.
