These AN flat washers by Pro-Werks are part of our specialty fasteners selection, made of non-hardened steel and cadmium plated (gold in color). AN washers have a smaller outside diameter than standard flat washers commonly found in industrial applications.
Their primary purpose in the aircraft industry is to provide a smooth bearing surface under a hex nut, allowing for index alignment of cotter pin holes or as shims to obtain the proper grip length needed on the fastener. Performance-minded builders also prefer AN washers for applications where space availability is limited and to save weight.
