Castle Nuts (or Slotted Nuts) feature slots (crenels) cut into one end. When used with a drilled shank bolt and a cotter pin, they provide a positive mechanical lock that prevents the nut from turning. This "fail-safe" mechanism is critical in high-safety environments like aircraft landing gear, wheel hubs, and steering linkages.
