Re: Broken Tork bolts
 

The body side torx bolts for the windshield frame had glued on nuts so
they can just be punched through. Those are the two on the body side of
the door post. A little heat can also just make them fall off the
inside.

I soak the broken bolts first in the best penetrating oil I can find.
Just a note, WD40 isn't a good penetrant.

Other than that, I take a punch and make a mark, then run an 1/8" bit
down the bolt, then one larger after. I normally soak these in oil
while drilling. I try hard to run the small bit slightly 'off' center,
I don't want it centered at all.

Then when I run a larger bit down through the bolt, it will hopefully
slightly tag the threads on one side of the bolt. This leaves a quarter
moon shaped chunk of metal in the hole that usually will just spin right
out.

Depending on how close I made the small hole, I used a 3/16" or a 1/4"
or a 5/16" bit for the 3/8" body bolts. Which ever one I think will
'just' skin the threads on the one side, but usually the 1/4" one is
right.

I have had very good luck using the above method on rust snapped bolts
and have seldom damaged the threads beyond re-use. I do use a thread
sealer like loctite on the new bolts to stop future rust.
