• Description:

  This is a genuine Ford camshaft sprocket bolt, a torque-to-yield fastener used on modular V8 engines across many Ford, Lincoln, and Mercury applications. The bolt secures the camshaft sprocket or, in some applications, the crankshaft pulley, clamping the component to its shaft so the timing drive transmits rotation accurately. As a torque-to-yield fastener it is designed to stretch to a precise clamp load when tightened to specification, which gives a consistent, secure joint in a high-stress location. Owners install this bolt whenever the camshaft sprocket or related component is removed during timing chain, cam phaser, or front-cover service, since torque-to-yield bolts are intended for single use and must be replaced rather than reused. Reusing a stretched bolt risks an inaccurate clamp load, loosening, or fastener failure at a critical timing component. Built to Ford specifications, the bolt provides the correct thread, length, and grade to install in the factory location without modification. Because this fastener is used across many modular V8 applications, confirm it matches your engine and component before ordering. Replace any washer specified with the bolt, follow the proper tightening procedure including any torque-plus-angle step, and use a new bolt each time the joint is disturbed for a reliable clamp.
