A smaller nut is tightened over the main nut, and by loosening, the main nut is forced against the smaller one to create friction locking.A partial slot is cut into the center of the nut, which is then compressed by tightening a screw to lock it.A nylon or hard fiber insert is embedded in the nut, which threads tightly onto the bolt to secure it firmly.Slots are cut through the top of the nut, allowing a cotter pin to be inserted through the nut and a hole in the bolt; the pin is then split and bent backward to lock it in place.None of the above.

Explanation

A castle nut is secured by cutting slots at its top, through which a cotter pin is inserted passing through a hole in the bolt. The pin is then split and bent back to prevent the nut from loosening, ensuring a reliable locking method.
