I am concerned about this, and you are correct in returning it for another. Would you mind helping me understand a little better what happened? Did the screw just keep turning when you screwed it into the nut? What stripped, the screw or the nut? It is a small screw; is there any possibility it was overtightened just a bit? I want to pass on whatever you can tell me to our Quality Control people to research. Thanks for your help, and again, I am so sorry about this. Gary
