A DIN 935 castle nut (or castellated nut) is a specialized hex nut featuring a notched, cylindrical top that resembles a medieval castle's battlements. It is designed to create a "positive locking" connection that is virtually impossible to loosen accidentally. An split pin is normally used with the nut.
