The M10 square plate washer is fabricated from thick galvanised steel, offering excellent durability and corrosion resistance. Its large 50mm x 50mm surface area provides a greater contact zone than standard round washers, ideal for structural wood fastening such as joist work and decking. The washer is designed for heavy‑duty applications and includes a 2.3mm thickness for added strength.
