Full title and description
ГОСТ 11403-75 — Инструмент кузнечный для ручных и молотовых работ. Обжимки-верхники круглые. Конструкция и размеры (English title: Blacksmith's hand and hammer tools. Round top swages. Design and dimensions). This standard specifies the designation, basic construction features and dimensional series for round top swages used in blacksmith hand and hammer operations.
Abstract
Standard GOST 11403-75 establishes the form, key construction features and dimensional table for round top swages (обжимки‑верхники круглые) intended for manual and power‑hammer forging work. It defines sizes and basic design requirements rather than detailed material specifications or heat‑treatment processes.

Scope
The standard applies specifically to round top swages used in blacksmith hand and hammer work and sets out their constructional form and dimensional series. It is intended for designers, toolmakers and manufacturers of blacksmithing tools and for organizations performing forging operations that use standardized swages.
Key topics and requirements
- Definition and designation of round top swages (обжимки‑верхники круглые).
- Dimensional series and tolerances for nominal sizes (tables of overall and working dimensions).
- Basic shape and constructional requirements (profile, working face form and mounting features).
- Marking/identification conventions and interchangeability considerations for common sizes.
- Notes on intended application (manual forging and hammer‑press operations) and reference to related technical requirements standards.
Typical use and users
Used by blacksmiths, toolmakers, forging shops, manufacturers of hand and power forging tooling, and maintenance departments that repair or replace forging dies and swages. The standard helps ensure compatibility and interchangeability of commonly used round swages across workshops and suppliers.
