Nord-Lock Wheel Nuts
A tightened Nord-Lock wheel nut cannot loosen by itself, even under severe operating conditions.
How Nord-Lock Wheel Nuts Work
The washers pair have cam faces on one side and serrations on the other. When the wheel nut is tightened, the serrations on the lower washer are embedded into the mating surface. As the cam angle “α” is greater than the thread pitch “β”, a wedge-effect is created, allowing movement only across the cam faces. Any rotation of the wheel nut is blocked by the wedge effect of the cams.
"In an independent comparative test, Nord-Lock wheel nuts proved their outstanding performance compared to conventional wheel nuts."

About Nord-Lock Wheel Nuts
HIGHEST CORROSION RESISTANCE & cannot loosen by itself
The wheel nuts use Nord-Lock wedge-locking technology to secure wheels by maintaining a high clamp force, even under severe operating conditions. A tightened Nord-Lock wheel nut cannot loosen by itself. Nord-Lock wheel nuts are used on heavy on-road vehicles (buses, trucks, trailers, etc.) and off-road vehicles (tractors, farming equipment, mining equipment, forestry machinery, military vehicles, etc.).
