NORD-LOCK® WHEEL NUTS

Nord-Lock wheel nuts safely secure wheels on both on-road and off-road heavy vehicles by maintaining a high clamp force, even under extreme operating conditions.

How it works

THE DETAILED VIEW

When tightening, the bolt’s serrations are embedded into the mating surfaces. As the cam angle α is greater than the thread pitch β, a wedge-effect is created.

The washer’s serrations are embedded into the mating surfaces, allowing movement only across the cam faces while the wedge effect prevents rotation of the nut.

PASSING THE TEST

PROVEN EFFECTIVENESS

In tests, the Nord-Lock wheel nuts prove superior in securing wheel joints and maintaining clamp load.

The graphs display products tightened to 200 kN and the change in clamp load during 1000 load cycles.

In safe hands

FULL TRACEABILITY

From the laser mark, trace your washers' origins to raw materials and production controls for that batch.

RIGOROUSLY TESTED

Tested under extreme conditions by independent institutes and extensively certified to meet any bolting challenge.

AVAILABILITY

Nord-Lock’s technical support and global distribution reaches every corner of the world.

TESTING AND CERTIFICATION

Nord-Lock wheel nuts have been rigorously tested and approved by independent institutes as well as certification authorities. The Junker test is the most rigorous method for testing bolted joints.

During the Junker test, the tested products are tightened and the clamp force is monitored during 1000 load cycles. The conventional wheel nut rotates and loses most of its initial clamp load in the joint. The Nord-Lock wheel nut safely secures the wheel joint and maintains the clamp force.
