What are the hammer on nuts called?

Hi
Simple one for someone, I need to replace the bearings on our push chair wheels.

The fixing nut fitted has been hammered onto the bolt, I have seen these before when putting together (of all things) a Cossie Coupe for the kids, but I do not know the official trade name for them to do a search. As I will need to cut it off and replace it.

Anyone know?

Thanks

But even this listing does not seem to be able to name them!

Spire nuts is the brand name, spire used to be the main manufacturer in the uk, probably all Chinese now.
I used to have their catalogue vast range or there used to be.

I'm wondering now if they still exist or have they gone the way of most british manufacturing companies, I dealt with them and they were very helpful mind you I was working a for a major national company at the time. Spire was the registered trade Mark can't remember the actual name of the company ........now I've got to find out if they're still about !

Typical that the repair I need to make uses parts from a defunct company possibly!

Couldn't let it rest, going since 1965 that's them, the original manufacturers. They were there when things started to change from a design and manufacturing perspective especially in motor vehicles.

You can prise them off if you are lucky, keep it straight and lever on both sides, moving around

Hammer back on with a socket to spread the load
