Then, attach the tow hook stem to the hook using the provided hex bolt and washers. Apply the anti - seize compound as directed. Finally, mount the assembled hook onto your vehicle. Remember, this tow hook is not for recovery purposes. Avoid using it to tow heavy loads or in emergency recovery situations.
