Fasteners Washers Flat Washer Fender

A fender washer, though similar in shape to a standard washer, differs in that the outside diameter is traditionally much larger in proportion to the center hole. With this design, a fender washer can be placed under the head of a bolt or nut to help distribute forces applied when tightening. Zinc plated fasteners are the most common used plating. This ensures good rust-resisting qualities, appearance and low cost.
