• Description:

  This is a Ford special nut carried under base number W708770 (catalog base HN1) and finish code S436, used at the truck bed mounting points where the box bolts to the frame. Dealer catalogs list it as a nut, a mount bolt nut, or a special nut. Representative applications include F-350, F-450, and F-550 Super Duty trucks with the longer cargo boxes, and it supersedes the earlier N811629-S428 and W706639-S436 numbers; these are examples rather than a complete list. The nut clamps the bed mount hardware so the box stays located on the frame rails, and a loose or missing nut can let the bed shift, creak, or move relative to the cab. This is a single-use fastener that Ford specifies cannot be reused or reinstalled, so it should be replaced rather than refitted whenever the bed is removed. Because thread size and seat design must match the original, confirm this nut 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: Part cannot be reused/reinstalled.
