CASTLE NUT

The castle nut is commonly used on applications where the nut needs to be secured from backing off. It is used with a cotter pin inserted through a hole drilled in the shaft and through the slots in the nut. Castle nuts are most common in fine thread. A more avialable substitue is the Slotted Nut  the difference being the turned down top. 
Standard finish is Plain
