ForgeFix Square Plate Washer ZP

These Forgefix Square Plate Washers have a larger surface area than most round washers, making them suitable for heavy-duty fastening. They are ideal for use with Carriage Bolts in structural timber fastening applications such as joist work and decking.;The washers are bright Zinc Plated for increased resistance to corrosion.;APPLICATION;Many structural applications where timber to timber fastening is required. The large surface area distributes the load evenly under the bolt head.;Can be used with all types of bolts and nuts.;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 aluminium and stainless steels by their oxide layers.
