Hex Flange Head Bolt – Mopar (6104257AA)
The Mopar Hex Flange Head Bolt (6104257AA) is a Genuine OEM fastener engineered to provide secure, high-strength attachment for a wide range of components on compatible Chrysler, Dodge, Jeep, and Ram vehicles. Designed with an integrated flange head, this bolt distributes clamping force evenly across the mounting surface while eliminating the need for a separate washer. Manufactured to strict Mopar factory specifications, it ensures precise fitment and long-term reliability.
Constructed from high-strength automotive-grade steel with a corrosion-resistant coating (application dependent), the bolt is designed to withstand vibration, load stress, and harsh environmental conditions. The precision-machined threads ensure smooth installation and proper torque retention, helping maintain secure fastening under dynamic operating conditions.
The 6104257AA hex flange head bolt is developed as an OEM-specific fastening component, matching original thread pitch, length, head design, and strength grade. Maintaining factory specifications is essential to ensure proper fitment, load distribution, and secure attachment. Using incorrect or non-OEM bolts may result in improper torque, component misalignment, or reduced fastening integrity.
For professional technicians, installing a Genuine Mopar bolt 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 flange head bolt supports secure component attachment, maintains structural integrity, and resists loosening caused by vibration or repeated load cycles. Replacing worn, stretched, or corroded bolts promptly is essential for safe and reliable vehicle operation.
