I'm almost positive I didn't cross thread it...haha I won't garuntee it, but when I say it forces the socket off, I can screw the plug in with the socket on it and then the socket is hitting the head instead on going into the hole where the plug is going into, so I can only get the plug in a little ways and then it gets pushed off...I'm going to try using a thread chaser on it and see if they just need to be cleaned up a bit.
