• Description:

  This is a genuine Ford hex nut built on the HN1 base, cataloged under several names including Nut, Catalytic Converter Nut, and references in cab back panel hardware, reflecting the many assemblies it serves. It is a broadly shared threaded fastener documented across E-350, F-150, Ranger, Aviator, MKS, Zephyr, Mariner, Montego, and Mountaineer, so this listing should be treated as a multi-vehicle service nut rather than a single-model item. The nut provides the clamp load for whatever stud or bolt it is paired with in exhaust, body, and chassis locations. Ford specifies this nut cannot be reused once removed, so a fresh nut is required whenever the joint is opened; reinstalling the original risks a loosened or leaking connection because the locking feature is spent after first use. This part replaces W718714-S900. A missing or backed-off nut lets the secured component shift, rattle, or separate. Confirm the thread size and hardware callout for your application against your VIN 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.
