These 27mm Stainless Steel wheel nut covers are made to fit 27mm diameter wheel nuts, which are usually found on some of the midlift axles on lightweight axled tractor units, also some smaller rigids and Buses/Coaches with M18 wheel studs. They are available in sets of 12.
Please note: These are not a genuine Alcoa® Wheels product and although they fit the M18 Alcoa® Wheels Retro fit wheel nuts they will not fit fully over the large spigot washer.
