• Description:

  This is a genuine Ford mount bracket bolt, catalogued under base number 500634 with the S439 hex flange head bolt suffix, an M10 fastener used to secure mount brackets on the 2017 through 2025 Ford Super Duty F-350, F-450, and F-550 chassis. The flanged hex head spreads clamp load across the bracket so the mounted assembly stays firmly located under the heavy loads and vibration these trucks see in service. Owners and fleet technicians reach for this bolt when replacing a mount bracket, reassembling chassis or powertrain hardware, or chasing a rattle or shift at a bracketed joint after a component has worked loose. The integral washer face distributes preload evenly and resists loosening in a vibration-prone mounting location, keeping the joint tight through normal duty cycles. Manufactured to Ford specifications, the bolt matches the original M10 thread, length, and head profile and installs in the factory location without modification. Torque it to the value listed in the Super Duty workshop manual for the specific bracket joint, and inspect the mating bracket and threads for distortion, elongation, or corrosion before reassembly. Replace any fastener showing thread damage rather than reusing it, and verify the bracket is fully seated against its mounting surface before applying final torque so the clamp load is carried correctly.
