Who is BS EN 4122 - Self-locking shank nuts for ?
BS EN 4122 on self-locking shank nuts is useful for: 
- Aerospace parts manufacturers
- Shank nuts manufacturers
- Steel manufacturers
Why should you use BS EN 4122 - Self-locking shank nuts ?
Heat resistant steels are solid solution strengthened alloy steels for use at temperatures above 500 deg C and upto 750 deg C. As these steels are used over a certain broad temperature range, they are normally strengthened by the hardening mechanism of heat treatment, solid solution, and precipitation.
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 4122 specifies the characteristics of self-locking shank nuts in heat resisting steel FE-PA2601, silver plated on the thread, it can be used for various aerospace applications and thus you can ensure safety in your organization.
