WASHER-LOCK (Hyundai HN61E5-11150)

A worn lock washer can allow threaded fasteners to loosen under vibration, leading to joint failure. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HN61E5-11150. The washer type provides a locking function by creating axial tension between the fastener head and the mating surface. A common generic failure consequence is that a missing or deformed lock washer may result in gradual fastener back-out during operation. During routine service, a technician might find that a previously tightened bolt has lost clamp load due to a collapsed washer. Keeping a lock washer in sound condition helps maintain consistent clamping force in bolted assemblies. Verify the serial number or application, then call (562) 693-7748.
