Square washers are a type of washer that, as the name suggests, have a square shape rather than the traditional round shape. These unique washers are designed to provide a larger surface area and better distribution of the load, making them particularly useful in applications where heavy loads or pressure are involved. They are commonly used in construction and industrial settings, where they can help to prevent bolts or screws from pulling through the material they are fastened to. The square shape of these washers also helps to keep them from rotating or becoming loose, providing added stability and security in critical applications. Overall, square washers offer a practical solution for ensuring secure and reliable fastenings in a variety of settings.
