Nyloc Nut with a 3/4" UNF thread, used as a locknut on heavy suspension joints.

A nylon insert set into the crown of the nut deforms over the bolt thread as it is tightened, resisting loosening under vibration. It retains fixings such as the rear radius arm, the top link and the fulcrum and ball-joint mountings.

Frequently asked questions

What is the NY612041 Nyloc nut used for?

The NY612041 is a 3/4 inch UNF self-locking Nyloc nut used as a locknut on heavy Land Rover suspension joints. A nylon insert grips the bolt thread to resist loosening under vibration. It retains fixings such as the rear radius arm, the top link, and the fulcrum and ball-joint mountings.

Should this 3/4 inch UNF Nyloc nut be replaced each time?

Replace the NY612041 Nyloc nut whenever it's removed. The nylon insert deforms over the bolt thread on first tightening, so a reused nut won't lock reliably, a real concern on heavy suspension joints. Fit a new nut each time you disturb the radius arm or link fixings.

Which Land Rovers use this 3/4 inch UNF Nyloc nut?

This 3/4 inch UNF Nyloc nut fits the Land Rover Defender, Discovery 1 and Range Rover Classic. It's used on heavier suspension fixings like the rear radius arm, top link and fulcrum ball joint. Check the thread size on your existing nut to confirm before ordering.

The product name doesn't show a size, so what thread is this nut?

This Nyloc nut is the 3/4 inch UNF size, the largest used on Land Rover suspension locknut points like the rear radius arm. If your existing nut measures differently, you'll need another size, so check the thread before ordering. The 3/4 inch UNF spec is the key identifier.
