How do you screw a 2x4 at 90 degrees?

Nail the horizontal 2x4 into the vertical 2x4 about 1/4 of the way down from the top of the vertical 2x4, so they are at a 90 degree angle. The way I've been nailing this scenario is to just nail through the vertical 2x4 at a 0 degree angle, directly into the middle of the end piece of the horizontal 2x4.
