Use a left hand drill bit to extract. As the bit grabs the metal it spins
it counter-clockwise. Much safer than EZ outs which I don't trust. I've
done this with old bolts that break on my 72 Honda motorcycle.

Jason, here is a tip I learned working on similar screws over the last 50
years. Tape off the surrounding painted area. Apply a couple of drops of
penetrating lubricant to both sides of the damaged screw. Using a ⅛" drill

Is there room to get purchase with a pair of vise grips? You might be able to
simply unscrew. I might also try a sharpened punch and attempt to unscrew by
tapping with the hammer and punch the remaining head of the screw to the left.
Some WD40 or equivalent applied to the screw before starting
Thanks for the advice everyone
And Bill, your response is helpful.
However, I don't remember how it happened. I think I just leaned too much
into tightening the bolt when installing fenders and the head broke off.
It was a couple of years ago.
I'm not sure what my options are for having someone
I agree that Bill’s likely got the best advice here, though my default is
to try to cut a slot in it with a dremel or hacksaw if there’s enough bolt
body protruding from the boss - it looks like there is but the angle of
the photo makes it hard to tell for sure. Once there’s enough of a slot to

I agree with all of what Bill said, and I would like to know the answers to
his questions.
That being said, this is the easiest broken bolt situation one can have.
The eyelet is open on both sides, and the broken bolt can be extracted in
either direction without requiring a reverse-handed drill
It's a kind of delicate job with many opportunities to screw it up. I
would seriously consider how important it is for you to fix this issue
successfully. If it's not that important that you succeed, then go for
it. Worst case, you fail, and you effectively lose that attachment point

+1 on the EZ out. Best way to do that job. If you don't have one, you need one
anyway.

Try and EZ out. It's a brand of "screw extractor" that comes with a
reverse drill bit. There are other brands available, as well. Check
Google. I find that often just using the reverse drill bit is enough to
get those buggers loose.
Good luck!

On Thursday,
Jason,
My suggested process might be a bit complicated if you don't already have
the tooling. I've used a combination of a smaller drill bit and tap to
thread the inside of the sheared bolt and screw in a long enough threaded
bolt to lock both ends into the sheared bolt (still following?). I'm
