适用范围：This standard specifies the characteristics of two lug, counterbored, floating anchor nuts, with a self-lockingfeature achieved by forming the upper portion out-of-round, the dimensions of which are in conformity withISO 3209.These nuts are intended for use in aircraft assemblies, in which the fasteners are mainly subjected to shearloads. The counterbore of nuts with thread diameter equal to or greater than 4 mm is deep enough toaccommodate a bolt shank in excess of assembly thickness, as well as the incomplete threads.The 3 mm diameter nut has no counterbore.They are intended to be used with threaded parts of 1 100 MPa 1) tensile strength classification.The cadmium plating restricts the application to temperatures not exceeding 235 °C.
