The 690-669 is a flat washer that distributes fastener loads across mating surfaces in aircraft structural and systems assemblies. Placed beneath bolt heads or nuts, it prevents fasteners from pulling through softer materials and maintains proper clamping force in airframe connections. Steel construction provides durability in high-stress applications.
