Over the years, 'Minilite' wheels have been produced in different widths and offsets for the Mini, Mini Cooper and Mini Cooper S. They all take .625" diameter lug nuts, but the lengths vary. D625 = 7/8" shank; D625MED = 1" shank; D625LONG = 1.5" shank; D625XL = 2" shank.
Washer (included) takes up approx. 0.2" so reduced the stated shank length by the washer thickness to figure how much of the lug fits through the wheel.
Lug nuts sold "each."
