A Slotted Nut (also known as a Castle Nut) is a high-strength fastening nut designed with slots on the top to secure a cotter pin, preventing the nut from loosening under vibration, heavy load, or rotational force.
Commonly used in automotive hubs, machinery joints, agricultural equipment, and structural assemblies, slotted nuts offer maximum locking security for critical applications.
Known for their durability and safety, these nuts are ideal for heavy-duty mechanical systems.
