A damaged lock nut can allow fastened components to loosen during operation, leading to mechanical misalignment or failure. This aftermarket replacement part references Toyota catalog number TY00591-12449-81. It is a 3/8-inch lock nut with a plastic insert that resists vibration-induced loosening. The plastic locking element deforms around the bolt threads to maintain clamping force. If the nut fails to hold torque, the joint may separate, causing unexpected downtime or secondary damage. The item ships at approximately 0.018 pounds. Verify the serial number or application, then call (562) 693-7748.

Part number variants: TY00591-12449-81, ty00591-12449-81, TY005911244981, ty005911244981
