thanks a lot for the reply:

  1. yes I have used 2 steps to apply pre tension as outlined in the course you said. 
  2. I have defined individual Co ordinate system for each bolt and as you can see from image below it is not close to bonded contact region. 
  3. are there any other courses for bolts? I have been stuck on this issue for weeks now. Any help will be appreciated.
