The 5/8"-18 Slotted Nut is a precision-threaded fastening nut designed for secure mechanical assemblies that require locking with a cotter pin. The slotted design aligns with a drilled bolt or spindle, allowing a cotter pin to pass through and prevent the nut from loosening under vibration or movement. Built from durable steel with fine 5/8"-18 threads, this nut is commonly used in axles, hubs, agricultural equipment, and machinery where reliability and safety matter—because a nut that stays put is always preferable to one that decides to wander off mid-operation.
