These Forgefix Mickey Pins are a type of universal nail, suitable for fastening all manner of fixtures in place on masonry applications. They are also known as capping nails. Their washing head ensures solid fixing. The Mickey Pins are Zinc Plated for increased resistance to corrosion. APPLICATION: Designed for fixing steel channeling, plastic sheets & cable trays. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier & 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 substrate&8217;s 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 & stainless steels by their oxide layers.
