The hexagonal shape is designed to be driven by a wrench (spanner) and provides excellent torque when done so. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and acting as a sacrificial anode if this barrier is damaged. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.
