Hey, John. Have you ever used a left hand twist drill bit for screw extraction? I have about a 75 percent success rate with left hand bits for bolts that aren't to bad. The hard part is centering the bit.

@joby613 - I use them when ever I can. Just removed a bolt from a flywheel a couple of days ago using a left-hand drill bit.

i have a small around 6mm broken nut below the surface on my fuel tank near the pump... i dont think i wanna weld or do anything involving heat because its on top of the fuel tank... any ideas? i really need some help on this... i dont wanna change the whole tank because of this!

@NEVERENDS90 - you may have to change the tank, or at least take it out to remove the broken fastener

If you write a book about how to deal with broken bolts, I`ll by it! Good video

@fyfanharrusett - See if you can find a copy fo Sunnen's Complete Cylinder Head and Engine Rebuilding Handbook, I wrote it in 1998 - try ebay, because they are out of print.

Much better choice of sound for your title slides. If I had one suggestion, it would be to turn down the sound levels on the title slides to match the sound levels of the rest of the video. Thanks for showing the correct technique to remove a broken bolt. I have always wanted to know how to do that.

Torx bits make tolerable screw extractors if you don't have anything else.

Most of the time i weld a nut on , best way to remove broken bolts

How is called the "easy out punch tool thing" please?

[dotcomboyz4life]

Can I do this same method for alternator brackets?

The main problem extracting a broken screw `stub' stuck in is to drill a hole exactly at its centre when it is having a broken uneven face. To make even worse someone would have used a CENTRE & hammered pits to`ring it out' and failed miserably leaving havoc! A centre drill or twist drill break inside makes the situation mad! It is always easy to blame saying `You didn't drill exactly at the centre & You damaged the threads'(eg: Dia1/4"or 5/16"broken screws).I feel something more to be invented!
