Yes, almost all Subaru cars use metric bolts. The thread sizes of the lug nuts will vary based on the wheel studs. Therefore, you need metric Subaru lug nuts to fully secure the wheels. For example, the most common metric thread sizes of Subaru bolts are M12x1.25mm. A M12 means the width of the thread area and a 1.25mm means the thread pitch. It is usually measured in millimeters. Then a set of M12x1.25mm wheel nuts fit your Subaru car perfectly.

Since aftermarket wheels come with various lug seat types, the correct seat types will depend on the actual wheel. Stock Subaru lug nuts may no longer fit these new aftermarket rims. At this point, it is critical to figure out the different types of lug nuts. If the aftermarket alloy wheels have a 60-degree conical lug seat, the lug nuts should be tapered accordingly. This is helpful for you to make a wise decision about which variation is best for your particular requirement.
