What kind of torque did you put on it?

Yes, the stud threaded section is 1 1/4" long. The hole the stud slides into is 3 1/2" deep. I stayed above the block deck about 1/4" as not to scuff the deck if the cam tool I was using slipped.
BTW: The cam tool I purchased from Sears is a piece for crap. Good thing it's a Craftsman so I can bring it back.
So, I did some deep thinking about this yesterday. Unfortunately, I didn't have the light bulb moment until most places closed for the day.
Here's how I'm going to fix this. If it works I'll post pics.
I located left hand drill bits on
http://www.mcmaster.com/
They also have left hand taps and bolts!
I'm going to machine a drill bushing that doubles as a chuck for a (short) left hand drill bit. Sometimes during the drilling the threads will back out. If it doesn't,,,,,
I am going to use the left hand tap to cut threads in the pilot hole.
This sometimes will cause the threaded section to back out. If it doesn't,,,,
I am going to thread in a left hand grade 8 bolt. This will repair the broken bolt and give me a positive bite on the threaded section. If the bolt breaks I can just drill it again.
If I used an extractor and it breaks, I toss the block in the scrap pile.
Extractors = bad....

bolt = good...
