TS ISO 1703

TS ISO 1703 is a terminology standard for the naming of assembly tools used with screws and nuts. Its value lies in establishing a common technical vocabulary, so the same tool can be identified consistently in drawings, catalogues, and manufacturing documentation. The document is about names and terms, not about tool performance or test methods.

Why nomenclature matters in fastening tools

Assembly tools for screws and nuts form a broad family that includes spanners, sockets, screwdriver bits, and related tools used to apply manual or controlled fastening action. In technical communication, precise terminology helps distinguish tools by form, drive interface, and intended use. That distinction is important because seemingly similar tools may differ in how they engage the fastener and in the context where they are used.

Language coverage in this document

The standard gives the nomenclature in English and provides technically equivalent French terms as well. German, Italian, Spanish and Swedish equivalents are also included for information only. According to the document, only the English and French terms are considered ISO terms. This preserves a clear distinction between official terminology and informative multilingual equivalents.

• Supports consistent naming in technical documentation and catalogues.
• Helps align terminology across different languages.
• Clarifies distinctions among tool types within the fastening domain.
• Focuses on vocabulary rather than product requirements or testing.
