Flat washers evenly distribute pressure when a bolt or screw is tightened. Its thin, plate-shape increases surface area to prevent the loosening and pullout of a fastener. They also relieve surface friction and can be used as spacers when additional clearance between objects is necessary.
Standard flat washers provide a smooth surface under the head of a nut or bolt to prevent loosening and damage to the work surface. These round washers also minimize heat and friction during the installation of a threaded fastener. They are used for general purpose applications across a wide range of industries.
