ForgeFix Hexagon Nut ZP ForgeFix 100NUT4, These Forgefix Hexagon Nuts are bright Zinc Plated for increased corrosion resistance. The hexagonal shape is designed to be driven by a wrench spanner and provides excellent torque. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that in contrast to iron oxide 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 aluminium and stainless steels by their oxide layers.
