NUT - FLANGE - SERRATED (Hyundai HNXKDE-00392)

HNXKDE-00392: A damaged flange nut can compromise the security of bolted connections in mechanical assemblies. During inspection, a serrated flange nut may show signs of loosening if the serrations have worn flat. The flange nut type provides a built-in washer face to distribute clamping load, while the serrated underside resists vibration-induced loosening. Hyundai is the OE maker for this aftermarket replacement part, cross-referenced as HNXKDE-00392. A common failure consequence of a worn serrated nut is gradual fastener loosening under dynamic loads. Keeping a flange nut in sound condition helps maintain consistent joint preload over time. Verify the serial number or application, then call (562) 693-7748.
