Abstract / scope

The values laid down herein have been specified so as to satisfy the requirements laid down in ISO 5858 or ISO 8641 (depending on the classification of the nut). States the values for nuts, a self-locking feature achieved by forming the upper portion out-of-round and with the given classification. Is intended solely for the drawing up of product standards appropriate for aerospace use.
