hex screw

[MarylandMagnav45]

I put a hex screw into a hole, and I bought the wrong hex screw.  The size was right but the amount of threading was wrong (I NEEDED MORE).  Not realizing what I was doing, I proceeded to push the hex screw past the thread onto the cylinder portion.  Once I realized my mistake, I tried to back the hex screw out with my socket wrench but to no avail, it just continues to turn in circles.

I tried hitting the bottom of it with a hammer while backing it out.

I also tried holding the bottom and pushing upwards while turning it.

Nothing has worked.

Any ideas?

Can ya post a pic of it for reference?

I'm not fully understanding your situation. 

Have you tried using a magnet to hold the screw back to catch a tread to back it out.
Or a little non-permanent glue to hold the screw to the hex driver to get the treads to catch.

I ended up sawing it off, and I have to replace the shell connector.

I was unable to back it out, and a repair shop couldn't even do it.  I had pushed the hex screw past the threads, and I guess it sheared the threads, and it wouldn't back out at all.

Thanks.
