This nut features a hexagonal body with castellated (slotted) top for positive locking via cotter pin.

Installation requires aligning a castellated slot with the bolt-end hole, then securing with a cotter pin per maintenance manual specifications. The castellated design prevents loosening from vibration and flight loads.
