Wheel nuts secure the road wheels to the hubs and are available in standard zinc-plated, chrome, and stainless steel finishes. The nut specification depends on the wheel type, standard pressed steel wheels, Rostyle wheels, and aftermarket alloy wheels each using the same dome-head nut, but the thread pitch and taper angle must match the wheel's mounting holes.
Finish & Fitting
Chrome wheel nuts provide an attractive finish but require regular polishing to maintain their appearance, particularly during winter when road salt accelerates tarnishing, while stainless steel nuts are the more practical choice for a car driven in the British climate, maintaining their bright finish indefinitely without polishing and not corroding or seizing onto the wheel studs. MG logo-embossed nuts are available in both chrome and stainless steel, providing an authentic period detail.
When fitting wheel nuts, they should be tightened in a diagonal pattern rather than sequentially around the wheel to ensure the wheel seats evenly on the hub, and torqued to specification with a torque wrench, as an overtightened nut can stretch the wheel stud or distort the wheel mounting face while an undertightened nut allows the wheel to work loose, with wheel nut tightness rechecked after the first 50 miles of driving following any wheel removal.
