    Description
    Round Flat Washers
    Flat washers provides a larger circular bearing surface which helps prevent a nut or bolt head from pulling through the material. Flat washers are commonly used in any application using a bolt where two pieces of material are being drawn together. In addition, they are sometimes used as spacers. The washer size designates the diameter of hole in the center. Flat washers are used with bolts and washers of the same diameter, material, and finish.
