WASHER (Hyundai HNA403-202006)

A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. The Hyundai catalog reference HNA403-202006 identifies this part as an aftermarket replacement. This washer type provides a bearing surface for a fastener and distributes the load to prevent damage to the mating material. A common failure consequence is that a missing or deformed washer allows the nut or bolt to embed into the surface, reducing preload. During routine service, a technician may find that a crushed washer has caused a fastener to back out. Verify the serial number or application, then call (562) 693-7748. This part is listed as a hardware washer in the aftermarket category.
