Square Washer

Square Washers are flat, square-shaped metal pieces with a central hole that are used to distribute the load of a threaded fastener such as a bolt or screw. They are widely recognized for their ability to provide a larger surface area for load distribution compared to their round counterparts.

The larger bearing surface helps prevent pull-through and sinking into softer materials, making Square Washers particularly effective in construction and structural applications. They are often used in conjunction with other fasteners to enhance stability and alignment.
