BS EN 2752 is a European Standard series that discusses components used in the aerospace industry. The purpose of BS EN 2752 is to provide the best industry design requirements for self-locking nuts to ensure resistance in loosening under vibrations and torque.
BS EN 2752 specifies the characteristics of self-locking, two lug, fixed, reduced series anchor nuts, with counterbore.
BS EN 2752 on self-locking nuts for aerospace applications is useful for:
Anchor nuts are intended for use in aircraft assemblies subjected principally to shear loading. Anchor nuts offer a permanent nut element on the interior of the joint that can be screwed to a skin, access panel, or fairings. The counterbore can accommodate a bolt plain shank in excess of assembly thickness, as well as the incomplete threads.
BS EN 2752 provides you guidance on required characteristics including, configuration, dimensions, tolerances, material, and surface treatment, enabling you to standardize the dimensional and physical properties of anchor nuts.
BS EN 2752 provides you guidance on dimensions and masses for threads depending on their code and designation to ensure conformity with international standards and their requirements, enabling you to deliver self-locking nuts that are compatible with aerospace systems and installations.
By adopting BS EN 2752, you can develop and assess self-locking nuts to ensure stable operability and resistance to vibration in aerospace applications.
