NUT-LOCK (Doosan DWD411294B)

A damaged lock nut can allow threaded fasteners to loosen under vibration, leading to component separation or misalignment. During assembly, a lock nut resists backing off through a built-in deformation or nylon insert that creates friction on the bolt threads. The Doosan catalog reference for this aftermarket replacement part is DWD411294B. This nut type is commonly used in applications where sustained clamping force is critical. A loose fastener due to a worn lock nut may cause progressive wear or sudden failure of the joined parts. The item ships at approximately 0.02 pounds. Verify the serial number or application, then call (562) 693-7748.
