【How-to】How big is 13 mm

The 2017 Nissan Altima lug nuts are M12 X1. 25 with a 21mm hex. This means that the thread is an M12 pitch and 1.25 inches long, and You will need to use a 21mm socket to remove the lug nuts. I recommend using an impact driver to remove Your lug nuts because it can make quick work of stuck lug nuts that are torqued on.
