These standards from ANSI, ASME, ISO, SAE, and others address the materials, construction, and requirements for hex nuts for a variety of applications. This list addresses thin Hex Nuts.
This Standard covers the complete general and dimensional data for metric hex jam nuts recognized as American National Standard. The inclusion of dimensional data in this Standard is not intended to imply that all of the nut sizes in conjunction with the various options described herein are stock items. Consumers should consult with suppliers concerning lists of stock production hex jam nuts.

ISO 8675:2012 specifies the characteristics of chamfered hexagon thin nuts (style 0), with metric fine pitch thread, with nominal thread diameters from 8 mm up to and including 64 mm, with product grade A for sizes D 16 mm and product grade B for sizes D 16 mm.
This International Standard specifies the dimensions of hexagon slotted (castellated) nuts, reduced height, reduced across flats, with MJ threads, of classifications: 450 MPa l) /425 C 2) , 600 MPa 1) /235 C 2) , 600 MPa l) /315 C 2) , 600 MPa 1) /650 C 2) , 900 MPa 1) /235 C 2) , 900 MPa 1) /730 C 2) and 1100 MPa 1) /600 C 2) . These nuts are intended to be used with split pins in conformity with IS0 1234. This International Standard is only applicable for the compilation of aerospace product standards.
ISO 9618:2016 specifies the dimensions of hexagon slotted (castellated) nuts, reduced height, normal across flats, with MJ threads, of classifications: 450 MPa/120 °C, 450 MPa/235 °C, 600 MPa/425 °C, 900 MPa/235 °C, 900 MPa/315 °C, 900 MPa/650 °C, 1 100 MPa/235 °C, 1 100 MPa/730 °C, and 1 250 MPa/600 °C. These nuts are intended to be used with split pins in conformity with ISO 1234. ISO 9618:2016 is applicable for the compilation of aerospace product standards.
This International Standard specifies the dimensions of plain, hexagonal nuts, reduced height, reduced across flats. with MJ threads, of classifications: 450 MPa 1) /425 C 2) , 600 MPa 1) /235 C 2) , 600 MPa 1) 315 C 2) , 600 MPa 1) 650 C 2) , 900 MPa 1) 235 C 2) , 900 MPa 1) 730 C 2) and 1100 MPa 1) /GOO C 2) . Nuts provided with holes are intended to be used with lockwire in conformity with ISO 245. This International Standard is only applicable for the compilation of aerospace product standards. 1) Corresponds to the minimum tensile stress which the nut is able to withstand at ambient temperature without breaking or cracking when tested with a bolt of a higher strength class. 2) Maximum temperature that the nut is able to withstand, without permanent alteration to its original characteristics, after ambient temperature has been restored. The maximum temperature is conditioned by the material or by the surface treatment.
ISO 9609:2016 specifies the dimensions of plain, hexagonal nuts, reduced height, normal across flats, with MJ threads, of classifications: 450 MPa/120 °C, 450 MPa/235 °C, 600 MPa/425 °C, 900 MPa/235 °C, 900 MPa/315 °C, 900 MPa/650 °C, 1 100 MPa/235 °C, 1 100 MPa/730 °C, and 1 250 MPa/600 °C. NOTE 1 450 MPa, 600 MPa, 900 MPa, 1 100 MPa and 1 250 MPa corresponds to the minimum tensile stress which the nut is able to withstand at ambient temperature without breaking or cracking when tested with a bolt of a higher strength class. NOTE 2 120 °C, 235 °C, 425 °C, 315 °C, 650 °C, 730 °C and 600 °C corresponds to the maximum temperature that the nut is able to withstand without permanent alteration to its original characteristics, after ambient temperature has been restored. The maximum temperature is conditioned by the surface treatment. Nuts provided with holes are intended to be used with lockwire in conformity with ISO 245.
