Resumen:
This European 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 °C 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.
