The heavy-duty square washer provides a greater bearing surface than standard flat washers, effectively distributing the load at critical connections. These bearing plates transfer compressive forces between two structural elements.
They're ideal for hammer beam timber frames or timber trusses where tie rod elements are used. The King Post with Steel All Thread joinery also uses these structural washers. They provide a perfect way to strengthen your timber frame without sacrificing the beauty of traditional joinery.
Our square washers feature a hot-dip galvanized coating, protecting the plate from corrosion when exposed to the elements or treated lumber. You can also choose a black powder coat finish, which includes a galvanized layer underneath for equal protection.
