Fender Washers

Fender Washers

Category : Washers

Fender Washers are alike flat washers but the only difference is that these fender washers have comparatively large outside diameter in proportion to the center hole. With the oversized outer diameter, this fender washer provides more bearing surface while installed between the bolt and nuts to facilitate distributing the load further.

These washers are punched / stamped out of the sheet metal. BoltPort can manufacture these large flat washers in metric and imperial sizes with wide material options and customization.
