I was going to suggest the Timeserts but you beat me to it.  
Check Amazon. 
They had the best prices when I looked for one of these.  I ended up getting
them at the local Fastenal dealer (who also had the helicoils) but I think
Amazon would have been quicker.

Bolt jammed against the insert and came out with it attached.)
