Annotation of standard text ČSN EN 4178 (313243):

This European Standard specifies the characteristics of screws, pan head, six lobe recess, coarse tolerance normal shank, medium length thread, in titanium alloy, anodized, MoS2 lubricated.
Classification: 1 100 MPa 1) / 315 °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
