Square washers are flat, square-shaped plates with a central hole, designed to be used with bolts and nuts for improved load distribution. Their larger surface area provides greater bearing capacity compared to standard round washers, helping to prevent pull-through and material deformation—especially in timber, channel sections, and heavy-duty construction applications. By evenly spreading the clamping force, they maintain joint integrity and stability under high loads. Commonly used in construction, machinery, and industrial assemblies, square washers offer reliable support and long-lasting performance in demanding environments.
