LOCKNUT (Hyundai HN940800908)

A damaged locknut can compromise the security of a bolted joint, leading to loosening under vibration. During assembly, the locknut's prevailing torque feature resists rotation after initial tightening. The locknut type generally relies on a deformed thread or nylon insert to create friction. A common failure consequence is gradual fastener loosening, which may cause component misalignment or noise. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HN940800908. Verify the serial number or application, then call (562) 693-7748.
