scope:
This document specifies the characteristics of bolts, normal hexagonal head, coarse tolerance shank, short thread, in heat resisting nickel base alloy, aluminium IVD coated.
Classification: 1 250 MPa1/425 °C2.
1 Minimum tensile strength of the material at ambient temperature.
2 Maximum temperature that the bolt can withstand without continuous change in its original characteristics, after return to ambient temperature. The maximum temperature is determined by the surface treatment.
