Frequently asked questions

What is the Domed Nut and what is it used for?

The domed nut, also called an acorn nut, has a closed 5/16 UNF top that encloses the end of the stud or bolt it threads onto. It protects the exposed thread from corrosion and gives a tidy finished look on Land Rover Series applications.

What thread does this domed nut have?

This domed nut has a 5/16 UNF (Unified National Fine) thread. Make sure the stud or bolt you're capping is also 5/16 UNF, since a UNC or metric thread won't match. UNF was standard on Land Rover Series engines of this period.

Which Land Rovers use this domed nut?

This domed nut fits Land Rover Series, including Series II 2.0 diesel, Series II/IIA 2.25 petrol and Series IIA 2.25 diesel engine applications. It's a general finishing fastener, so confirm the thread and location on your vehicle before ordering.
