Hi,
What you need is a 12-point 12mm socket. See pic 1 below. However, I have found that regardless of how good the socket is, they are still loose. MAC tools make a special 12-point head bolt socket for Nissan that works well on these. You can try a regular 12-point socket, but if you suspect it may strip the bolt, don't use it.
The MAC part number is SC189R
If you have a 1/2" 12 point, try that before getting a new one. One other thing, make sure to follow the directions in pic 2 below.
If there is anything I can do to help, let me know.
Take care and Happy New Year.
Joe
