BS EN 4309 is a European standard on aerospace series that covers self-locking hexagon nuts with normal height and normal across flats in cadmium plated alloy steel.
BS EN 4309 specifies the characteristics of hexagonal nuts, self-locking by plastic ring, normal height, normal across flats, in alloy steel, cadmium plated.
BS EN 4309 on self-locking hexagon nuts is useful for:
A Locknut (self-locking nut, locking nut) is a nut which 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.
Cadmium Electroplating (Nadcap Accredited) Electroplated cadmium is a robust and versatile metallic coating. Cadmium is a soft white metal that, when plated onto steel, cast iron, malleable iron, copper, and powdered metal, functions as a "sacrificial coating," corroding before the substrate material.
BS EN 4309 specifies the characteristics of self-locking hexagon nuts with normal height and normal across flats in cadmium plated alloy steel. This can benefit you as this information is used in various aerospace applications. This can help you increase safety in operations.
