• Description:

  This is a Ford nut and washer assembly carried under base number W709923 and finish code S437, in an M8 size, used at decklid, hood, and door hinge positions. Dealer catalogs name it as a nut, a hinge nut, or a hex nut and washer assembly. Representative applications include Mustang and Transit Courier in upper and lower hinge positions built from the early 2010s onward; these are examples rather than a complete fitment list. The captive washer spreads clamp load across the hinge mount so the panel stays aligned and the hinge does not loosen with repeated use. A loose or missing hinge nut lets the lid, hood, or door sag, bind, or shift out of alignment in its opening. Because the integrated washer and thread must match the hinge stud, using the correct nut keeps the panel positioned and torqued as designed. Confirm this part against your VIN or a Ford parts diagram before ordering so the hinge is secured correctly. This is a multi-year service part that fits across the model years of the listed Ford applications.
