Plain Flat Washers

Plain Washers (also called as Flat Washers) are simple circular disc with a center hole for bolt allowance. These flat washers are the most standard choice for most fastening applications. As the name suggests these washers have almost flat surface with perfect grip for the bolting joint.

Plain washers are manufactured in metric and imperial size with standard and heavy thickness for high strength bolting. Flat washers are produced by die punching sheets, plates or strips of required material specification and trimmed for rough edges or sometimes can be machined from bar stock.
