Nyloc Nut with a 1/2" UNF thread, used to retain suspension and steering ball-joint fixings.

A nylon insert set into the crown of the nut deforms over the bolt thread as it is tightened, resisting loosening under vibration. It secures joints such as the radius arm and link fixings, shock absorber mountings, the top link and fulcrum, and the steering box.

Frequently asked questions

What is the NY608041L 1/2 inch UNF Nyloc nut used for?

The NY608041L is a 1/2 inch UNF self-locking Nyloc nut used to retain Land Rover suspension and steering ball-joint fixings. A nylon insert grips the bolt thread to resist loosening under vibration. It secures joints like the radius arm and links, shock absorber mountings, the top link and fulcrum, and the steering box.

Can this ball joint Nyloc nut be reused?

Replace this 1/2 inch UNF Nyloc nut every time it's removed. The nylon insert deforms over the bolt thread on first tightening, so a reused nut can loosen under vibration, a real risk on steering and suspension ball joints. Always fit a new nut when you disturb these fixings.

Where is the 1/2 inch UNF Nyloc nut used on the vehicle?

This 1/2 inch UNF Nyloc nut is used across the suspension and steering on the Land Rover Defender, Discovery 1, Series 3 and Range Rover Classic. Typical points include the rear radius arm and links, shock absorber mountings, the top link and fulcrum ball joint, and the steering box.

How do I know I need the 1/2 inch UNF nut rather than another size?

Check the thread on your existing nut. This is the 1/2 inch UNF size used on ball-joint and heavier suspension fixings. Land Rover used several Nyloc sizes close together, so measuring the bolt thread before ordering avoids fitting the wrong nut on these suspension joints.
