Overview
ISO 262:2023 is an international standard specifying the selected sizes for ISO general purpose metric screw threads used in bolts, screws, studs, and nuts. Covering diameters from 1 mm up to 100 mm, this standard defines diameter and pitch combinations based on ISO 68-1 profiles and selected from ISO 261. It serves as a critical reference for metric commercial fastener screw threads ensuring interchangeability, quality, and global consistency.
This third edition of ISO 262 updates the 1998 version by expanding available sizes to include larger diameters (68 mm to 100 mm) and refines designation guidelines in line with current ISO protocols. The document supports manufacturers, engineers, and quality assurance professionals involved in fastener design and production.
Key Topics
- Diameter and pitch selections: ISO 262 outlines first and second choice pitch options for nominal diameters ranging from 1 mm to 100 mm. These dimensions facilitate standardized metric thread applications for mechanical fastening systems.
- Basic and design profiles: The thread forms conform to ISO 68-1 standards, guaranteeing proper fit, strength, and functional reliability.
- Designation system: The standard refers to ISO 965-1 for thread designation to maintain consistent identification practices worldwide.
- Normative references: Related ISO standards such as ISO 261 (general plan for metric threads) and ISO 5408 (thread vocabulary) provide foundational terminology and technical framework.
- Scope of application: The standard is intended specifically for commercial metric fasteners used in general purpose mechanical assemblies, ensuring broad applicability across industries.
Applications
ISO 262:2023 is essential for sectors relying on metric threaded fasteners, including:
- Automotive manufacturing: Securing engine components, chassis, and accessories with standardized bolts and nuts.
- Machinery and equipment: Establishing reliable mechanical joints in industrial machines, tools, and assembly lines.
- Construction: Fastening steel structures and mechanical systems where strength and interchangeability are critical.
- Electronics and appliances: Providing precise screw threads for assembly and servicing of electrical devices.
- Maintenance and repair: Facilitating replacement parts with compatible threaded fasteners to prolong equipment lifecycle.
By adopting ISO 262, organizations streamline procurement, reduce inventory complexity, and ensure thread compatibility across international markets, promoting operational efficiency and reducing engineering errors.
Related Standards
ISO 262 works in conjunction with several other international standards to fully define metric screw threads:
- ISO 68-1: Defines the basic and design profiles of general purpose metric screw threads.
- ISO 261: Establishes the general plan for metric screw threads including thread series and pitch.
- ISO 965-1: Details the tolerances and designation rules for metric screw threads to ensure interchangeability and quality control.
- ISO 5408: Provides vocabulary related to screw threads, aiding clear communication and understanding between stakeholders.
These standards collectively support the global harmonization of metric screw thread specifications, fostering innovation and consistency in fastener technologies.

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.
