Frequently asked questions

What is the NY605041L self-locking nut used for?

The NY605041L is a 5/16 inch UNF self-locking nut with a 1/2 inch across-flats hexagon. Its self-locking action resists loosening under vibration and holds clamp load without a separate lock washer. It's a general-purpose imperial fastener used across classic Land Rovers like the Series 2 and 3, Discovery 1 and Range Rover Classic.

Can this self-locking nut be reused or should it be replaced?

Replace it. Self-locking nuts like this typically lose their grip once they've been run onto a bolt, because the locking feature wears as the nut is tightened and removed. Fitting a new nut each time keeps the vibration resistance that stops the joint working loose.

What thread does the NY605041L nut have?

The NY605041L has a 5/16 inch UNF thread with a 1/2 inch across-flats hexagon, so it needs a 1/2 inch AF spanner or socket. Being an imperial UNF fastener, it won't fit metric studs or bolts, which matters on older Land Rovers that mix imperial and metric threads.
