Aerospace series - Screws@ pan head@ offset cruciform recess@ close tolerance normal shank@ short thread@ in alloy steel@ cadmium plated - Classification: 900 MPa (at ambient temperature)/235 °C (Edition P 2)
This European standard specifies the characteristics of screws@ pan head@ offset cruciform recess@ close tolerance normal shank@ short thread@ in alloy steel@ cadmium plated. Classification: 900 MPa1)/ 235 ??). 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.
