①,Historical nuts with D<M5 and D>M39, not conforming to ISO 898-2 nor to ISO 3506-2 .

These historical nuts should not be used for new or critical applications (e.g. tightening near or above the yield limit, dynamic loading); they are only included for referral to existing documents.Mechanical properties are not specified in ISO 898-2 and ISO 3506-2 for nuts with sizes D<M5 and D>M39; Therefore, the property classes specified in ISO 898-2 and ISO 3506-2 cannot be used for these nuts which are not conforming to the requirements of ISO 898-2 and ISO 3506-2. Nevertheless, if the use of such nuts is considered, the mechanical properties and related tests to be performed as well as the relevant marking and labelling are to be defined by agreement between the purchaser and the supplier at the time of the order.
