I bought the Kappa 2101, did some reading here while I was waiting for it to arrive, and found this thread.
Thanks for posting it up! I took precautions based upon your lessons learned, and got that bolt out cleanly.
Hammer drill did nothing. Old school impact driver didn't turn it, but I believe that it broke the stick on the Loctite red that was on the threads. I ground a hex bit head flat so it would seat fully, and using a breaker bar, got it to come free finally.
Took a tap to the threads to clean out the hole and that was necessary, couldn't spin the bolt in otherwise.
Thanks for passing on the lessons learned!
