The washers are bright zinc plated for increased corrosion resistance and have been given the name 'Penny Washer' due to their similarity in size to an old penny. Washers provide a smooth surface for the nut or bolt to bear on, making it less likely to loosen as a result of an uneven fastening surface. The main purpose of a washer is to distribute the load under a bolt head or the nut face. These can be used with all types of bolts and nuts. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish by forming a barrier and acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that does not trigger a breakdown of the substrates surface integrity as it is formed. 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.
