Square Plate Washers
Square plate washers are made of just low carbon steel. These washers have a larger surface area compared to round washers. Since they develop more friction when tightened against wood, these washers are normally used in seismic applications. They are mostly used in timber construction. At BBI, we have stock sizes available for bolts of diameter from 1/2″ to 1″ & thickness of 0.195″ to 0.395″. Experts in our team recommend hot-dip galvanized plates to ascertain maximum corrosion resistance.
