A damaged lock nut can compromise the security of a bolted joint, leading to loosening under vibration. During assembly, a lock nut resists rotation through a built-in mechanical locking feature, such as a nylon insert or deformed threads. The catalog reference for this aftermarket replacement part is Mitsubishi part number MB1063090. This nut type is generally used to prevent fasteners from backing out in dynamic applications. A common failure consequence is gradual loosening, which may cause component misalignment or detachment. This item ships at approximately 0.042 pounds.
