Malleable washers are specialized, oversized fastening components that feature an extra-large bearing surface area. This unique design serves a crucial purpose: preventing bolt heads and nuts from sinking or embedding into wooden surfaces during installation.

These washers are typically used in dock construction and various wooden structural projects. Manufactured from malleable iron, which offers excellent durability and load distribution, these washers come in multiple finishes to suit different needs - including plain, zinc-coated, or galvanized options for enhanced corrosion resistance.
