What Are AN Washers?
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.
