Square Plate Washers

Square Plate WashersSquare plate washers are made from low carbon steel and have a larger surface area than round washers. Since they develop more friction when tightened against wood, this type of washer is specified for seismic applications. They are often found in timber construction.

Available in the following finishes and sizes:
Plain, Zinc Plated, Hot Dipped Galvanized, Black Oxide, Silicone Bronze, Yellow Zinc, Aluminum, 316 SS, and 304/18-8/410 SS.
