• Description:

  The W700212-S437 is a genuine Ford hex nut built on the HN2 nut base, used as a suspension fastener at the top of a strut or shock and at control-arm attachment points. Dealer catalogs carry it under the dominant name Top Nut in the suspension and steering section, and on parts diagrams it is also listed simply as Nut - Hex. Documented sample applications where this exact service number is cataloged include the Ford Fusion, Police Responder Hybrid and SSV Plug-In Hybrid and the Lincoln MKZ, with catalog notes specifying the sport suspension and left/right positions; treat those as representative examples rather than a complete vehicle list, because Ford reuses one nut across many suspension assemblies and model years and does not publish a single finite fitment chart for it. A strut or control-arm top nut carries the clamp load that holds the damper or arm to the body or knuckle; when it is loose, corroded or missing, the suspension joint can knock, shift under load, or allow alignment to drift, and a buyer chasing a clunk or a loose strut is usually looking for exactly this nut. Replacing it with the correct genuine nut restores proper clamp load at a safety-critical joint. Because the suffix code denotes a specific thread size, finish and locking feature, confirm fit for your exact vehicle by VIN before ordering rather than relying on the sample applications above.
