- Description:
This is the genuine Ford pulley bolt, the fastener that secures a drive pulley, such as the main accessory or alternator pulley, to its shaft so the pulley stays clamped and spins the accessory drive reliably. Cataloged by Ford as a pulley bolt, it clamps the pulley to the correct torque so it does not loosen under belt load and keeps the accessory drive turning smoothly. It spans a 15-25 window across applications with the 5.0L and 5.2L engines, including performance and supercharged builds, making it a genuine multi-vehicle service fastener. Owners look for this bolt when the original has been stripped, corroded, or lost during pulley or accessory-drive service, or when a pulley must be reinstalled with correct hardware. Because it clamps a rotating component under belt tension, using the correct grade and thread is essential for a secure, reliable joint. A missing or improper pulley bolt can allow the pulley to loosen, causing belt misalignment, noise, or accessory failure. As a genuine Ford fastener it matches the original thread, length, and grade so it torques correctly to the shaft. Installing the correct bolt restores a secure pulley mount. Confirm the engine and pulley application against your vehicle before ordering.
