Overview
ISO 4042:2022/Amd 1:2026 is an amendment to the international standard governing electroplated coating systems for fasteners, published by the International Organization for Standardization (ISO). This amendment updates specifications relating to electroplated coatings, focusing on corrosion protection for fasteners-a critical element for industrial, automotive, and construction sectors where component durability and reliability are essential.
Electroplating fasteners with specialized coatings such as Zinc-Nickel (ZnNi) helps enhance their corrosion resistance, extend service life, and ensure consistent performance in various demanding environments. This amendment specifically addresses technical details in coating system classifications as outlined in ISO 4042:2022.
Key Topics
- Electroplated Coating Systems: The document pertains to requirements and classifications for electroplated coatings on fasteners, ensuring they conform to modern corrosion protection standards.
- ZnNi Iridescent Passivation: The amendment introduces and clarifies the application of ZnNi (Zinc-Nickel) coatings with iridescent (silver grey) passivation, including both standard and sealed variations.
- Transparent Passivation: A significant update highlights that a transparent passivation (An) can be applied to ZnNi coatings. This method achieves comparable corrosion protection with thinner layers, compared to traditional, thicker iridescent passivation.
- Corrosion Protection: The focus remains on providing high-quality corrosion resistance for fasteners, supporting extended service life in challenging settings.
- Clarification via Table Footnotes: The amendment adds clarifying footnotes in relevant coating classification tables, promoting standard clarity and better guidance for manufacturers and users.
Applications
The updates provided in ISO 4042:2022/Amd 1:2026 are essential for organizations involved in:
- Manufacturing and Supplying Fasteners: Companies producing bolts, nuts, screws, and similar hardware benefit from standardized coating requirements, ensuring product quality and global compatibility.
- Automotive Industry: Ensures fasteners in vehicles resist corrosion, contributing to safety and longevity.
- Construction and Engineering: Enables the selection of appropriately coated fasteners suitable for both indoor and outdoor structural applications.
- Maintenance and Repair Operations (MRO): Provides clear guidance for the replacement and specification of coated fasteners in equipment and infrastructure.
- Quality Assurance and Compliance: Companies certifying compliance with ISO fastener standards will rely on the clear, updated coating specifications now included in the standard.
By adhering to the latest amendment, stakeholders ensure compatibility with industry best practices and alignment with evolving corrosion protection technologies.
Related Standards
Organizations referring to ISO 4042:2022/Amd 1:2026 may also benefit from consulting these related standards:
- ISO 4042:2022 – The base standard for fasteners and electroplated coating systems, providing comprehensive requirements.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
