The flat washers are crafted by fine workmanship for smooth surface, to distribute the pressure of the nut or bolt evenly over the part being secured,
reducing the chance of damage thereto, and to provide a smooth surface for the nut or bolt to bear on,
making it less likely to loosen as a result of an uneven fastening surface.
