• Description:

  Fog Lamp Assembly U-Nut – Ford (W520802-S439)

  The Fog Lamp Assembly U-Nut – Ford (W520802-S439) is a Genuine OEM fastening component manufactured by Ford Motor Company, engineered to provide secure and reliable mounting for fog lamp assemblies on compatible Ford vehicles. Designed to meet exact factory specifications, this U-nut ensures proper alignment and retention of fog lamp hardware during installation and long-term vehicle operation. This part is sold individually.

  Manufactured from high-strength, corrosion-resistant steel, the W520802-S439 U-nut is built to withstand road vibration, moisture, temperature changes, and environmental exposure commonly found in front-end and exterior mounting locations. The spring-steel design allows the nut to clip securely onto body panels or brackets, creating a threaded anchor point where traditional nuts are not accessible. This design supports consistent torque application and helps prevent loosening over time.

  For professional mechanics, using the correct OEM U-nut is essential when replacing or reinstalling fog lamp assemblies. Ford-specified fasteners ensure proper fitment, correct thread engagement, and factory-level retention strength, eliminating the risks associated with mismatched or universal hardware. This contributes to efficient installation and helps maintain original assembly standards.

  DIY mechanics benefit from the ease of installation and confidence that comes with using a factory-approved component. The U-nut installs cleanly without modification, simplifying fog lamp repairs or replacements while ensuring the assembly remains securely mounted and properly aligned.
