What is a Castle Nut?

A Castle Nut is a specialized hex nut with slots (or notches) cut into one end. These slots align with a drilled bolt and allow the insertion of a cotter pin, preventing the nut from loosening under vibration or load. Castle nuts are commonly used in automotive, aerospace, construction, machinery, and structural applications.
