Fender Washers

Boker’s is a stamping manufacturer of fender washers. 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. Its oversized outside diameter also provides more bearing surface for the load of the fastener—distributing the load further on soft or thin materials. Fender washers are commonly used in automotive, sheet metal, plumbing and electrical applications.

Fender washers have an outside diameter much larger in proportion to the center hole.

Boker’s fender washers are offered with outside diameters ranging from 0.081 inches to 5.000 inches, plus numerous inside diameter and thickness options. With ready access to more than 2,000 commonly specified and difficult-to-find materials, Boker’s delivers fender washers in materials including low-carbon sheet steel, various spring steels, stainless steel, aluminum, brass, copper and nickel silver.
