Hex Head Bolt and Coned Washer – Mopar (6508065AA)

The Mopar Hex Head Bolt and Coned Washer (6508065AA) is a Genuine OEM fastening assembly engineered to provide secure, load-distributing attachment for a wide range of components on compatible Chrysler, Dodge, Jeep, and Ram vehicles. This combination integrates a hex head bolt with a coned (dished) washer, allowing for controlled clamping force, improved load distribution, and enhanced resistance to loosening under vibration. 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 bolt and washer assembly is designed to withstand vibration, load stress, and environmental exposure. The coned washer design helps maintain consistent tension by compensating for minor surface irregularities and thermal expansion, while the precision-machined threads ensure smooth installation and proper torque retention.

The 6508065AA hex head bolt and coned washer is developed as an OEM-specific fastening component, matching original thread pitch, bolt length, washer profile, and strength grade requirements. Maintaining OEM specifications is essential to ensure proper load distribution and secure attachment. Using incorrect or non-OEM fasteners may result in uneven clamping force, loosening, or component misalignment.

For professional technicians, installing a Genuine Mopar bolt and washer assembly 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 hex head bolt and coned washer supports secure component attachment, maintains structural integrity, and resists loosening caused by vibration or repeated load cycles. Replacing worn or damaged fasteners promptly helps ensure safe and reliable vehicle operation.
