适用范围：This standard specifies requirements for closed corner, counterbored, fixed, reduced series anchor nuts, witha self-locking feature achieved by forming the upper portion out-of-round.These nuts are intended for use in aircraft assemblies, in which the fasteners are mainly objected to shearloads. The counterbore is deep enough to accommodate a bolt shank in excess of assembly thickness, aswell as the incomplete threads.They are intended to be used with threaded parts of 1 100 MPa 1) tensile strength classification.The cadmium plating restricts the application to temperature not exceeding 235 °C.
