Square washers are essential in load-bearing applications due to their ability to distribute pressure more evenly across a material. The larger surface area of square washers reduces the risk of material deformation, which is especially important in construction projects involving wood, concrete, or metal. By preventing localized stress, square washers ensure that bolts stay securely in place without damaging the surrounding material.
These washers are also designed to resist rotation, providing enhanced stability and preventing loosening under vibration or pressure. This makes square washers particularly valuable in high-stress environments like steel construction and heavy machinery assembly, where structural integrity is paramount.
