NUT-LOCK (Toyota TY005904499671)

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 Toyota part number TY005904499671. This nut type is commonly used in applications where sustained clamping force is critical. A generic failure consequence is that a loose fastener may allow adjacent components to shift or separate. The item ships at approximately 0.17 pounds. Verify the serial number or application, then call (562) 693-7748.
