BS EN 3672 is a European standard on aerospace series that covers self-locking shank nuts in heat resisting nickel base alloy NIP101HT (Waspaloy).
BS EN 3672 specifies the characteristics of self-locking shank nuts in NI-P101HT, silver plated, for use in 30° cone holes, for aerospace applications.
BS EN 3672 on self-locking shank nuts is useful for:
Lock nuts (also known as prevailing torque nuts or stiff nuts) are resistant to vibration & torque. They are primarily available in stainless steel and other finishes. Their locking action is created by the distortion of their uppermost threads and should resist loosening caused by shock, vibration and other forces.
Waspaloy is a precipitation hardening, nickel-based alloy which has been used in elevated temperature applications. The alloy has been used for gas turbine engine parts which require considerable strength and corrosion resistance at temperatures up to 1600°F (871°C).
BS EN 3672 specifies the characteristics of self-locking shank nuts in NI-P101HT, silver plated, for use in 30° cone holes. This can benefit you as this information is used in various aerospace applications. This can help you increase safety in operations.
