Looks like its M8 x 30? so wont be one of the "non essential" guards or covers or radiator/fans i dont think. Not one of the belt tensioner bolts maybe, or water pump?

Also did you take any of the cam seal caps off to change the seals? They might be around that size.

It’s probably a water pump bolt, serpentine belt tensioner bolt, timing belt tensioner bolt.
