scope:
This European standard specifies the characteristics of screws, pan head, offset cruciform recess, coarse tolerance normal shank, long thread, in alloy steel, cadmium plated, for aerospace applications.
Classification: 1 100 MPa1/235 °C2.
1 Minimum tensile strength of the material at ambient temperature.
2 Maximum temperature that the screw can withstand without continuous change in its original characteristics, after return to ambient temperature. The maximum temperature is determined by the surface treatment.
