Lock Nut – Mopar (6509799AA)

The Mopar Lock Nut (6509799AA) is a Genuine OEM fastener engineered to provide secure, vibration-resistant fastening for a wide range of components on compatible Chrysler, Dodge, Jeep, and Ram vehicles. Designed with an integrated locking feature, this nut helps maintain consistent clamping force and prevents loosening under dynamic loads. Manufactured to strict Mopar factory specifications, it ensures precise fitment and long-term reliability.

Constructed from high-strength automotive-grade steel with corrosion-resistant coating (application dependent), the lock nut is built to withstand vibration, load stress, and environmental exposure. The internal locking mechanism—such as a prevailing torque design or nylon insert (application dependent)—helps maintain thread tension and ensures reliable fastening performance over time.

The 6509799AA lock nut is developed as an OEM-specific fastening component, matching original thread pitch, diameter, and strength grade requirements. Maintaining OEM specifications is essential to ensure proper torque retention and secure attachment. Using incorrect or non-OEM fasteners may result in loosening, thread damage, or compromised component stability.

For professional technicians, installing a Genuine Mopar lock nut ensures compliance with manufacturer assembly and safety standards during repair or replacement procedures. For experienced DIY vehicle owners, selecting the OEM fastener eliminates compatibility concerns and restores factory-level fastening performance without modification.

A properly installed lock nut supports secure component attachment, maintains structural integrity, and resists loosening caused by vibration or repeated load cycles. Replacing worn or damaged lock nuts promptly helps ensure safe and reliable vehicle operation.
