Full title and description

St ISO 225-2010 rus — Fasteners — Bolts, screws, studs and nuts — Symbols and descriptions of dimensions (Russian-language edition of ISO 225:2010). The standard defines the common symbols and the descriptive names of dimensions used for bolts, screws, studs and nuts to be used in product standards and technical drawings; figures are provided as illustrative examples.

Abstract

ISO 225:2010 (edition 3) gives standardized symbols and descriptions of the dimensional features of bolts, screws, studs and nuts, and supplies equivalent terms in several languages including Russian for use in product standards and engineering drawings. The illustrations are examples only; the standard is intended to ensure consistent representation and terminology across product standards and technical documentation.

Scope

This standard specifies the symbols and gives descriptions of the dimensions of bolts, screws, studs and nuts for use in product standards and on engineering drawings. It covers the names and symbolic designations of key dimensional features (for example head dimensions, shank/major diameters, thread lengths, nut heights and flats) and provides multilingual term equivalents for clarity in international use. Figures provided are illustrative; product-specific standards may provide additional dimensional rules or tolerances.

Key topics and requirements

• Standardized symbols for components and dimensions of bolts, screws, studs and nuts (heads, shanks, threads, fillets, etc.).
• Definitions and descriptive names for dimensional features used on drawings and in product standards.
• Examples of profile and dimensional callouts for common fastener types (illustrative figures only).
• Multilingual equivalents (official ISO languages: English, French, Russian; additional equivalents in several other languages for information).
• Intended use as a reference for product standards, technical drawings and specification documents to ensure consistent terminology and symbols.

Typical use and users

Used by mechanical engineers, design drafters, technical authors, standards committees, fastener and component manufacturers, quality and inspection personnel, and procurement specialists who need consistent dimensioning, terminology and symbols for fasteners in international product standards and drawings.

Related standards

Closely related standards include general thread and fastener specifications and mechanical/property standards such as ISO 261 / ISO 262 (metric thread designation and tolerance), ISO 898-1 (mechanical properties of bolts and screws), ISO 3506 (corrosion‑resistant stainless steel fasteners), and various product-specific fastener standards (hexagon socket screws, thread run-out, etc.). Regional/adopted versions include EN/EN‑ISO adoptions and national translations/adoptions (Russian-language national providers). These related references are commonly cited alongside ISO 225 in product standards and technical dossiers.

Q: Who typically uses it?

A: Mechanical designers, drafters, standards writers, fastener manufacturers, quality/inspection staff, and procurement professionals who need unified dimensioning and terminology for fasteners in drawings and specifications.

Q: Is it current or superseded?

A: ISO 225:2010 is the current (edition 3) version published in 2010 and has been subject to the normal ISO systematic reviews; it replaced the withdrawn 1983 edition. Users should confirm if their national body has any more recent adoption notes or amendments before use.

Q: Is it part of a series?

A: It is part of the suite of ISO standards covering threads and fasteners (e.g., ISO 261/262 for metric thread designation/tolerances, ISO 898 and ISO 3506 for mechanical properties). ISO 225 is a reference for symbols and dimension descriptions used across those product standards.
