Overview
ISO 4095:1998 is an international standard developed by the International Organization for Standardization (ISO) specifically for the aerospace industry. It outlines the metric series wrenching configuration dimensions for bihexagonal (double hexagon) drives used in aerospace applications. This design standard provides clear guidance for the dimensions, form, and allowable variations for bihexagonal drives, ensuring compatibility, reliability, and interchangeability in aerospace fastener systems.
Key Topics
Bihexagonal Drive Configuration
Defines the standardized geometric characteristics of double hexagon drives, commonly used in high-performance aerospace fasteners and components.Metric Series Dimensions
Specifies critical dimensions expressed in millimetres, ensuring consistency in manufacturing and inspection of aerospace wrenching elements.Tolerances and Material Conditions
Establishes permissible variations in size, form, and position for bihexagon profiles within specified limits, including maximum and minimum material conditions.Designation of Drives
Provides a uniform system for identifying and specifying bihexagonal drive sizes, supporting clear communication in technical documentation and procurement.Reference to ISO 286-2
Cites standards for tolerance grades and limit deviations to maintain geometric precision and mechanical performance.
Applications
ISO 4095:1998 is essential for manufacturers, suppliers, and maintenance organizations in the aerospace sector. Its practical applications include:
Design and Manufacturing
- Ensures that aerospace fasteners such as nuts and bolts with bihexagonal drives are designed to standardized dimensions, improving fit and assembly efficiency.
- Guides tooling and machining of wrenching configurations, reducing the risk of errors during production.
Quality Assurance and Inspection
- Provides measurable parameters for verifying conformity of fasteners and wrenching tools, supporting consistent quality across global supply chains.
- Facilitates reliable interchangeability of fastener components produced by different manufacturers.
Maintenance and Repair
- Enables easy identification and replacement of aerospace fasteners during maintenance through standardized sizing and designation systems.
- Supports safe and efficient servicing of aircraft and space vehicles by ensuring that tools and components are compatible.
Procurement and Logistics
- Improves efficiency in ordering and inventory control by referencing standardized drive sizes and configurations.
- Reduces ambiguity and potential errors in technical contracts and engineering drawings by providing a clear metric basis for specification.
Related Standards
Professionals utilizing ISO 4095:1998 may also benefit from understanding related standards, such as:
- ISO 286-2: System of limits and fits - Tolerance grades and limit deviations for holes and shafts, referenced for tolerance classes within ISO 4095:1998.
- Other Aerospace Fastener Standards: Explore additional ISO and IEC standards covering aerospace fastener systems, geometric characteristics, testing, and material requirements.
- ICS 49.030.01: The standard falls under the International Classification for Standards for fasteners, useful for broader research and cross-referencing.
ISO 4095:1998 ensures global consistency in the design and production of aerospace bihexagonal drive elements. Adherence to this standard enhances reliability, quality, and safety in aerospace components and supports seamless collaboration among global industry partners.

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 4095 was prepared by Technical Committee
ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 4, Aerospace
fastener systems.
This second edition cancels and replaces the first edition (ISO 4095:1978),
