  Bolt Bearing Cap Hex Head

• Description:

  This genuine Ford engine crankshaft main bearing cap bolt is the side cross fastener that threads horizontally into the side of the main bearing cap on the 5.0L Coyote V8, tying the cap laterally into the block's deep skirt to resist side loading and keep the main bearing bore round and stable under high rpm and combustion loads. It is a hex-head bolt that threads into the side of the main bearing cap, and it fits 2011-2025 Ford 5.0L Coyote V8 applications including Mustang GT and F-150 5.0L. The Coyote lower end relies on three distinct fasteners in the base 6345 family per cap, and this side bolt works alongside the vertical bottom cap bolt and the main cap stud to fully lock the girdle in place. Builders need this bolt during a bottom-end rebuild, main bearing repair, crankshaft replacement, or any time a cross bolt was over-torqued, stretched, corroded, or damaged. A yielded or reused fastener cannot hold correct clamp load, which can allow cap walk, bearing crush loss, and bearing failure. This is a single-use torque-to-yield fastener: never reuse it, always install a new bolt torqued to Ford's exact specification with the specified lubricant, as reusing a stretched fastener risks loss of clamp load and catastrophic engine damage. Cataloged by Ford as the Engine Crankshaft Main Bearing Cap Bolt. Backed by the Ford genuine parts warranty.
