Nyloc Nut with a 5/8" UNF thread, used as a self-locking fastener in the suspension linkage.

The nylon insert deforms around the bolt thread on assembly, gripping it to resist loosening under vibration and repeated load reversal. This provides a secure, self-locking fixing without a separate lock washer. Applied as a bottom link securing nut.

Frequently asked questions

What is the NY610041L nyloc nut used for?

The NY610041L is a 5/8 inch UNF nyloc (nylon-insert) lock nut. The nylon collar grips the thread to resist loosening from vibration. On these Land Rovers it's typically used as a suspension bottom link nut and other 5/8 inch UNF fixings.

Can a nyloc nut be reused?

Nyloc nuts are single-use by design. Once the nylon insert has been threaded and torqued, it deforms and loses grip, so reusing it risks the joint loosening. Fit a fresh 5/8 inch UNF nyloc every time the fastener is removed.

How many NY610041L nuts do I need?

Order one per 5/8 inch UNF fixing in your job. Suspension bottom link work typically uses them in matched quantities per side, so replace all that you disturb rather than reusing the old nuts.

How do I confirm this nut fits my application?

The NY610041L suits Defender up to 2016, Discovery 1, and Range Rover Classic 1986-1994 as the suspension bottom link nyloc nut. On Defender 90 the bottom link application runs to VIN KA930434. Confirm the thread is 5/8 inch UNF.
