Description
Plain washers can also be used when the hole is bigger than the nut. The main role of flat washers is to increase the size of a screw’s bearing surface area and reduce the surface pressure applied on the fastened object. The most common type of washers is plain washers, also known as flat washers. Looseness can result when the bearing surface sinks under the surface pressure, so using a flat washer to reduce the surface pressure is very effective. Common examples of plain washers include fender washers, spherical washers, wall washers, and torque washers.
