Frequently asked questions

What is the NY604041L nyloc nut used for?

The NY604041L is a 1/4 inch UNF nyloc (nylon-insert) lock nut. The nylon collar grips the thread to resist vibration loosening. It's a general-purpose fixing used across many points on these Land Rovers, including track rods, dampers, and body fixings.

Can the 1/4 inch nyloc nut be reused?

Nyloc nuts are single-use. The nylon insert deforms the first time it's torqued, so a reused nut won't grip reliably and can work loose. Fit a fresh 1/4 inch UNF nyloc each time the joint is opened.

How many NY604041L nuts do I need?

Order one per 1/4 inch UNF fixing you're working on. Because these nuts shouldn't be reused, replace every one you remove rather than refitting the old nuts. They suit Defender, Discovery 1, Range Rover Classic, and some Jaguar applications.
