What is BS EN 4297 - Self-locking hexagon nuts about ?
BS EN 4297 is a European standard on aerospace series which covers self-locking hexagon nuts in corrosion resisting steel.
BS EN 4297 specifies the characteristics of hexagonal nuts, self-locking by plastic ring, normal height, normal across flats, in corrosion resisting steel, passivated.
Who is BS EN 4297 - Self-locking hexagon nuts for ?
BS EN 4297 on self-locking hexagon nuts is useful for: 
- Aerospace parts manufacturers
- Self-locking hexagon nut manufacturers
Why should you use BS EN 4297 - Self-locking hexagon nuts ?
A Locknut (self-locking nut, locking nut) is a nut that resists loosening through vibration and normal use. This trait makes them essential hardware for a multitude of applications. Unlike free spinning nuts, lock nuts make use of a deforming elastic or metal material to stay in position against torque and shock.
Steel has a certain resistance against corrosion. This so-called passivity is due to a thin and invisible layer of oxides being formed on the surface. This process takes place through a reaction between the metal and the oxygen in the surrounding environment.
With the help of BS EN 4297 which specifies the characteristics of self-locking hexagonal nuts, by plastic ring, normal height, normal across flats, in corrosion resisting steel, you can benefit from the use of the information in various aerospace applications. This can help you increase safety in operations.
