• Description:

  This is a Ford U-nut listed under base number W708991 (catalog base HM1) and finish code S439, used to retain fender liners, wheel opening moldings, and related splash components. Dealer catalogs name it as a nut, a fender liner U-nut, or a hex U-bolt nut, and it is often supplied with the fender liner itself. Representative applications include Bronco, F-150, and F-350 Super Duty along with Lincoln Corsair, Mark LT, and Navigator in front and lower positions; these are examples rather than a complete fitment list. The U-nut clips onto a panel flange and provides a threaded anchor for a screw or bolt, holding the liner snugly against the fender. A missing or sprung U-nut lets the liner sag, flap at speed, or contact the tire. Because the flange thickness it grips and the thread it accepts must match the original, confirm this part against your VIN or a Ford parts diagram before ordering. This is a multi-year service part that fits across the model years of the listed Ford applications.

• Notes: Included with fender liner. Included with Wheel opening molding.
