OEM Part
OEM: Made by an Original Equipment Manufacturer. This part is made by an original equipment manufacturer or under their license, ensuring compatibility and quality.
Nyloc Nut - 3/8 UNF self-locking nut with a nylon insert in the collar. The insert grips the bolt thread and resists loosening under vibration.

Used across the driveline and chassis fixings: differential housing and carrier fixings, propshaft flange fixings, steering wheel and column fixings, chassis frame fixings and towing bracket fixings.

Supplied as a pack of 100. The individual nut is part number NY606041L.

A nyloc nut is a single-use fastener. The nylon insert deforms as the nut is first tightened and does not reliably re-lock, so fit a new nut on reassembly.

Frequently asked questions

What is the NY606041L nyloc nut used for on Land Rovers?
NY606041L is a 3/8 UNF nyloc nut used across multiple systems on the Defender, Discovery 1, Range Rover Classic, and Range Rover P38. Typical applications include the front and rear differential, propshaft, frame assembly, and steering column.
Can nyloc nuts be reused, or do they need replacing each time?
Nyloc nuts are typically single-use fasteners. The nylon insert that provides locking resistance deforms on first installation and won't grip reliably if reused. Best practice is to fit new nyloc nuts when reassembling differential, propshaft, or steering components.
Why is this sold as a pack of 100?
The pack of 100 (NY606041LX) is intended for workshops and fleet operators. The 3/8 UNF nyloc nut appears frequently across Defender, Discovery 1, and P38 assemblies, so a bulk pack makes it practical to always fit fresh fasteners.
