• Description:

  This is a Ford nut listed under base number W709771 (catalog base HN1) and finish code S440, used on an adjusting screw where a threaded nut sets or locks a position. Dealer catalogs name it as a nut, an adjusting screw nut, or a nut-adjusting screw. Representative applications include Bronco, F-150, and Mustang along with Lincoln Navigator; these are examples rather than a complete fitment list. The nut threads onto an adjusting screw to hold a setting, which is common in linkage, latch, or alignment hardware where a component must be positioned and then locked. A loose or missing adjusting nut lets the setting drift, so whatever the screw controls can fall out of adjustment over time. Because the thread must match its adjusting screw exactly and the seat style governs how it locks, using the correct nut keeps the adjustment stable. Confirm this nut against your VIN or a Ford parts diagram before ordering so it matches the adjusting screw in the application. This is a multi-year service part that fits across the model years of the listed Ford applications.
