Muteki Open Ended Lightweight Lug Nuts - 12x1.25. These Muteki lug nuts are very similar to the Kyokugen nuts, just spline drive instead of seven sided. Open ended in case you are running longer studs. Includes locking key socket for install and removal.

After many questions about diameter size, I decided pictures speak louder than words. Here is the width of the nut with socket (~20mm).

Please specify color via drop-down menu when ordering. Available in Black, Chrome, and Blue.
