NISSAN 40222-C6001 Wheel Hub Bolt

The genuine OEM part with part number NISSAN 40222-C6001 is a premium-quality wheel hub bolt (wheel stud) that plays a critical role in the safe operation of the vehicle. This high-strength fastener ensures the stable and secure attachment of the wheel rim to the wheel hub, reliably transmitting driving and braking forces.

Technical Features and Properties

Genuine Nissan wheel studs are engineered and manufactured to the strictest automotive standards, guaranteeing maximum tensile strength and an exact fit:

• Material Quality: Specially heat-treated, high-strength steel alloy resistant to extreme shear and tensile stresses.
• Surface Protection: Specialized anti-corrosion coating (galvanized or phosphated layer) protecting the component from moisture, road salt, and environmental elements.
• Design: Press-in (knurled shoulder) design that seats firmly into the wheel hub bore, preventing the bolt from spinning when tightening the lug nut.
• Thread Profile: Precision-rolled threads for maximum load-bearing capability and smooth assembly.

Function and Importance

Wheel studs are directly responsible for the integrity of the connection between the vehicle and the road surface. In operation, they are continuously exposed to dynamic loads, vibration, and high temperatures generated by the braking system. Utilizing genuine OEM parts guarantees that the thermal expansion and strength ratings perfectly match the vehicle's factory engineering specifications.

Signs of Failure or Wear

Damaged wheel studs pose a severe safety hazard. Immediate replacement is required if any of the following symptoms occur:

• Damaged or Stretched Threads: Frequently caused by incorrect tightening torque (overtightening with an impact wrench) or cross-threaded lug nuts.
• Visible Cracks or Deformation: Structural damage resulting from metal fatigue or excessive load.
• Severe Corrosion: Heavy rust weakens the material's structural integrity, which can lead to fracture.
• Damaged Knurling: Occurs when the stud spins within the hub flange during tightening or loosening.

Safety Recommendation: When replacing wheel studs, always adhere to the manufacturer-specified tightening torque using a calibrated torque wrench.
