ForgeFix FORFPNUT8 Hexagonal Nuts & Washers ZP M8 Forge Pack 16 These Hexagon Nuts and Washers are bright zinc plated for increased corrosion resistance. The hexagonal shape of the nut is designed to be driven by a wrench (spanner) and provides excellent torque when done so. The washer distributes the load of a the nut and helps to reduce vibration. 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 substrate’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 and stainless steels by their oxide layers.
