Frequently asked questions

What is the NT605061L thin nut used for?

The NT605061L is a reduced-height 5/16 inch UNF hex nut. Its shallow profile suits fastening points with limited clearance, and it's commonly run against a standard full-height nut as a jam nut to resist loosening under vibration. It fits Series 2 and 3, Defender up to 2016, Discovery 1 and Range Rover Classic.

How is a thin nut used as a locknut?

A thin nut like the NT605061L is typically run down first, then a full-height nut is tightened against it so the two jam together and resist vibration. This jam-nut method locks the thread where a taller locking nut won't fit.

How do I confirm the NT605061L fits my Land Rover?

The NT605061L 5/16 inch UNF thin nut fits the Land Rover Series 2 and 3, Defender up to 2016, Discovery 1 and Range Rover Classic. It cross-references to codes 254861, 254881 and 345930. Match the thread and clearance at your fastening point before ordering.
