BS EN 2894 specifies the characteristics of self-locking bihexagonal nuts, with counterbore, in heat resisting nickel base alloy, passivated, MoS2 lubricated.
BS EN 2894 is a European metallic material standard for aerospace applications.
BS EN 2894 on self-locking bihexagonal nuts is applicable to:
Self-locking bihexagonal nuts are resistant to vibration and torque. Locknuts are reusable a limited number of times as the prevailing torque declines each time the nut is used. BS EN 2894 gives you guidelines on the locknuts that you would use in production.
BS EN 2894 specifies the characteristics of self-locking bihexagonal nuts and creates a standardized approach for manufacturers of self-locking bihexagonal nuts to adhere to if they supply their metallic materials to the aerospace and defence industry.
BS EN 2894 guides you in the surface treatment process of aerospace products to maintain product quality. By adopting BS EN 2894, you can demonstrate the reliability of your aerospace products, and build trust in their use throughout the aerospace supply chain.
