The height of the prevailing torque feature ( h max – m min ) for the non-metallic insert is identical for regular, high and thin nuts for a given diameter. If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.
