Aerospace series Screws@ pan head@ six lobe recess@ coarse tolerance shank@ medium length thread@ in alloy steel@ cadmium plated Classification: 1 100 MPa (at ambient temperature) / 235 °C (Edition P 2)
This standard specifies the characteristics of screws@ pan head@ six lobe recess@ coarse tolerance shank@ medium length thread@ in alloy steel@ cadmium plated. Classification: 1 100 MPa 1) / 235 ??2). 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.
