The odd thing that strikes me is that the thread has deformed upwards, towards the head. I would definitely refit the bolt without the injector to ensure it goes in further than the injector body. It might be that the bottom of the threaded hole has damaged the thread. If this is the case then removing some material from the bolt thread will help.
