The Simpson Strong-Tie Square Plate Washer which measures 50 x 50 x 2.5mm (L x W x T) is made from pre-galvanised mild steel. The material is known for its formability and resistance to corrosion. It has a M12 bolt hole and increases the strength of bolted connection to timber. Bearing plates give greater bearing surface than standard cut washers helping to distribute the load more effectively. The square plate allows it to cover a larger area on the surface area as compared to round washers tha
