It is commonplace though to use them on bare timber, the squared section giving enough grip to prevent rotation. Carriage bolts are extensively used in security fixings where the bolt must only be removable from one side. The smooth domed head and square neck below prevent the carriage bolt from being unlocked from the insecure side.
