WASHER (Hyundai HN4942278)

A worn washer can allow fastener loosening under vibration, leading to component misalignment or detachment. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HN4942278. The washer functions as a load-distributing spacer placed under a nut or bolt head. Its plain mechanical role is to reduce surface pressure and prevent galling between the fastener and the mating part. A common failure consequence is gradual loosening of the joint, which may cause rattling or eventual separation of secured components. The item ships at approximately 0.002 pounds. Verify the serial number or application, then call (562) 693-7748.
