Overview
ISO 13589:1998 specifies the dimensions of aerospace bihexagonal (double‑hex) nuts that are self‑locking, have a counterbore, and use MJ threads. The standard covers multiple nut classifications defined by minimum tensile stress at ambient temperature and the maximum service temperature (for example: 1 100 MPa / 425 °C, 1 550 MPa / 600 °C, etc.). Dimensions are given in millimetres and apply after any surface coating but before lubricant application. ISO 13589 is intended for use in the compilation of aerospace product standards.
Key topics and requirements
- Configuration: Bihexagonal (double‑hex) nut with counterbore and MJ thread form; self‑locking achieved by forming the upper portion out‑of‑round.
- Dimensional data: Detailed nominal sizes, wrenching codes and associated maximum/minimum dimensions, provided in figure/table format (mm).
- Classifications: Multiple material/strength‑temperature classes identified by a tensile stress at ambient temperature and a maximum allowable temperature (e.g., 1 210 MPa / 730 °C).
- Measurement conditions: Dimensions and tolerances apply after any surface coating(s) and before lubricant application.
- Tolerances and form: Tolerances of form and position to conform with ISO 8788; thread limits referenced to ISO 5855‑2.
- Interoperability: Dimensions determined to satisfy procurement specifications ISO 5858 (≤425 °C) or ISO 8641 (>425 °C) depending on classification.
- References: Normative references include ISO 4095 (wrenching configuration), ISO 5855‑2 (MJ thread limits), ISO 5858, ISO 8641 and ISO 8788.
Applications and users
ISO 13589 is practical for:
- Aerospace fastener designers and mechanical engineers specifying nut geometry and fit for high‑temperature and high‑strength applications.
- Procurement and quality assurance teams enforcing dimensional conformity for supplied nuts.
- Manufacturers and machinists producing bihexagonal self‑locking counterbore nuts with MJ threads.
- Maintenance, repair and overhaul (MRO) facilities ensuring replacement parts meet aerospace interchangeability and temperature/strength class requirements.
Common application areas include airframe and engine bolted assemblies where controlled locking performance and high‑temperature resistance are required.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 13589 was prepared by Technical Committee
ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 4, Aerospace
fastener systems.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération
mondiale d'organismes nationaux de normalisation (comités membres de
l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une
étude a le droit de faire partie du comité technique créé à cet effet. Les
organisations internationales, gouvernementales et non gouvernementales,
en liaison avec l'ISO participent également aux travaux. L'ISO collabore
étroitement avec la Commission électrotechnique internationale (CEI) en
ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques
sont soumis aux comités membres pour vote. Leur publication comme
Normes internationales requiert l'approbation de 75 % au moins des
comités membres votants.
La Norme internationale ISO 13589 a été élaborée par le comité technique
ISO/TC 20, Aéronautique et espace, sous-comité SC 4, Éléments de
fixation pour constructions aérospatiales.
