Topic: Broken bolt removal -

[Redeyejedi]

i am cleaning up the knuckles to prepare them and i noticed a bolt broken off. any suggestions on how to remove it?

Buy a broken bolt extractor. The one I like is a Snap-On that uses reverse drill bits and an extractor.

easy-out, or at least thats what I've always known them as.

with one of these guys,   you can find them by the drill bits at any hardware store.

You just drill a tiny hole in the bolt, tap it in then unscrew it.

i think you'll need a reverse tap to do that

[86rustbucket]

No I mean you just tap the extractor in with a hammer after you drill a small hole in the center of the broken bolt.     then turn it

Before you start spray it with some penitrating fluid the night before.

got it!
thanks guys!


i don't know why in my mind i thought yall were talking about these, and im like how do i use them here?


so to sum up...
after i posted originally, before i left to get the extractors, i heated the bolt up a bit, then sprayed pb blaster and ran a candle on it to allow wax to get sucked in with the penetrating catalyst.
it soaked for aprox 35 min.
went at it with the drill bit, broke one, but got to the bottom.
used the extractor and out it came, 8sec, with minimal effort.
thanks again.
:cheers:

PB Blaster is where its at....

Soak the bolt with a 50/50 mixture of acetone and ATF for a day or more, then try drilling out with a left hand drill bit.  McFadden Dale Industrial Hardware sells these bits for around $5.00, but you have to ask for them as they are kept behind the counter, at least at the store I go to.  Usually the broken fastener will start to spin back out with the drill bit without damaging the hole.  Has worked for me very well.  Depending on where and what you are trying to remove heat works also.
