Slotted Nut

A slotted nut is a specialized hex nut with multiple vertical slots machined into its top portion. These slots are designed to align with a hole drilled through the mating bolt, allowing a cotter pin or wire to be inserted. This creates a positive mechanical lock, preventing the nut from rotating or loosening under severe vibration and dynamic loads.
