ISO 4035 Hexagon Thin Nuts Chamfered

ISO 4035 Equivalent Standards

ISO 4035 Scope

This International Standard specifies the characteristics of chamfered hexagon thin nuts, with threads from M1,6 up to and including M64, with product grade A for threads d < M16 and product grade B for threads d> M16.
If in special cases, specifications other than those listed in this International Standard are required, they should be selected from existing International Standards, for example ISO 724, ISO 898-2, ISO 965-1, ISO 3506-2 and ISO 4759-1.
