ČSN EN 2811

This European Standard specifies the characteristics of steel, cadmium plated hexagonal nuts, with an upper portion slotted or castellated normal height, normal across flats. These nuts are intended for use in aircraft assemblies subjected principally to shear loading. They are intended to be used with threaded parts of 1 100 MPa 1) tensile strength classification and split pins to EN 2367. The cadmium plating restricts the application to temperatures not exceeding 235 °C. 1) This strength level applies at ambient temperature.
