BS EN 4123 is a European standard on aerospace series which covers shank nuts, self-locking in heat resisting nickel base alloy NI-PH2601.
BS EN 4123 specifies the characteristics of self-locking shank nuts in NI-PH2601, silver plated on thread, for aerospace applications.
Classification: 1 550 MPa1 / 600 °C2.
BS EN 4123 on self-locking shank nuts is useful for:
Nickel-based alloys are materials that are composed mainly of nickel and some other alloys. Ni-based alloys are known for their excellent corrosion resistance and strength. They are often found in high-temperature environments due to their superior resistance to heat.
Shank nuts are high-temperature, high tensile strength nuts that are used primarily in aircraft engine applications. Shank nuts are self-locking, self-retaining, self-wrenching nuts installed by flaring the nut shank with a conical tool.
As BS EN 4123 specifies the characteristics of self-locking shank nuts in heat resisting nickel base alloy NI-PH2601, silver plated on thread, it can be used for various aerospace applications and thus you can ensure safety in your organization.
