Overview
ISO 6043:1985 - "Shipbuilding and marine structures - Eye and fork assemblies under tension load - Main dimensions" specifies the main dimensions, material grades and designation rules needed to ensure interchangeability of eye, fork and associated bolts or pins used under tension loads in shipbuilding and marine structures. First published in 1985, the standard covers dimensional tables (in millimetres), tolerance classes and material minimums for components used on cargo handling and lifting appliances. It is explicitly not applicable to components subject to compressive thrust or torsional loads.
Key topics and requirements
- Main dimensions and interchangeability
- Nominal sizes and corresponding main dimensions are tabulated for eyes, forks and connections (dimensions given in millimetres).
- A figure illustrates the permitted shape and key dimensional references for assembly parts.
- Designation and coding
- Simple designation rules for parts: code letters A (eye), B (fork), C (connection) plus nominal size (e.g., Eye ISO 6043 - A 10; Fork ISO 6043 - B 10; Connection ISO 6043 - C 10).
- Materials
- Eyes and forks: minimum steel grade Fe 360 per ISO 630.
- Bolts and pins: minimum steel grade Fe 430 per ISO 630.
- Option to use quenched & tempered (heat-treated) steels per ISO/R 683/1 when higher quality is required.
- Tolerances and fits
- Dimensional tolerances follow tolerance grade IT14 of ISO 286.
- Clearance hole-related dimensions are aligned with ISO 273 (fasteners - clearance holes).
- Scope limits
- Intended for components subject to tension only (examples: round-hole eyeplates, sheave block head fittings, block holders, trunnion pieces, turnbuckles).
- Securing methods for bolts/pins are left to national regulations.
Applications and who uses it
- Practical applications:
- Design and manufacture of shipboard lifting gear, rigging connections, cargo handling fittings and related marine hardware where predictable interchangeability and load-bearing performance under tension are required.
- Typical users:
- Shipbuilders, marine engineers, naval architects, rigging and hardware manufacturers, classification societies and ship repair yards.
- Benefits:
- Ensures dimensional compatibility between suppliers, supports safe load-bearing assemblies, and simplifies specification in technical drawings.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 6043 was prepared by Technical Committee ISO/TC 8,
Shipbuilding and marine structures.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.

nationales par le Conseil de I’ISO. Les Normes internationales sont approuvées confor-
