I FIXED IT. This time around I did things differently.
You have to use the washers provided by union NOT the black ones providied by burton that you get with the 13mm screws.
Plus you have to use a #3 screw driver (duh). You may think a #2 will work but it wont get the screws tight enough. USe a number 3.
Use some threadlock of some sort.
