ISO 20929:2018 Overview
ISO 20929:2018 is an international standard established by the International Organization for Standardization (ISO) that defines specifications for heel guidings (side friction plates) used in large stamping and forming dies. These components are critical tools for guiding the movement of die components during heavy pressing operations, ensuring precision and safety in metal forming processes.
The standard specifies the dimensions, material requirements, and typical applications of heel guiding plates, providing a uniform basis for manufacturing, ordering, and using these essential die components. It is intended for manufacturers, engineers, and quality control professionals involved in toolmaking for large-scale stamping and forming industries.
Key Topics Covered
Dimensions and Design
- Standardized dimensional ranges for heel guidings, including width, thickness, and length.
- Design features such as guiding grooves, friction surfaces with solid lubricants, and corresponding mounting holes.
- Considerations for tooling with inclined planes to ensure accurate engagement of heel guidings.
- Typical fastening components such as hex socket head screws (ISO 4762) for secure attachment.
Material Specifications
- Heel guidings may be made from:
- Hardened steel, typically C45E steel with superficial hardening to approximately 58 HRC, including embedded solid lubricant inserts covering 20%-25% of the friction surface.
- Self-lubricating bronze, conforming to EN 1982, also with solid lubricant inserts.
- The materials ensure wear resistance under heavy load and durability during forming operations.
Applications
- Heel guidings facilitate alignment between upper and lower die plates in large or medium stamping/forming tools.
- They improve the guidance system beyond traditional cylindrical guide pins by also absorbing shear forces.
- Used during tool transport to immobilize die plates, preventing accidents or damage.
- Recommended in setups where high lateral forces are not exceeding certain thresholds; otherwise, a more robust side clamp (serre-flanc) may be preferred.
Practical Applications
ISO 20929:2018 heel guidings provide critical support to metal forming and stamping industries by:
- Enhancing tool precision: By maintaining alignment between die components, heel guidings improve product accuracy and reduce scrap rates.
- Increasing tool lifespan: Hardened materials and lubricated surfaces minimize wear and maintenance downtime.
- Ensuring safety: Immobilizing die components prevents accidental displacement during transport, protecting operators and equipment.
- Simplifying design and ordering: Standard dimensions and clear designation guidelines streamline procurement and replacement processes for tooling shops.
- Supporting customizable solutions through varied sizes, accommodating diverse tool designs to fit specific industrial needs.
Related Standards
ISO 20929:2018 works in conjunction with related international and European standards for comprehensive tooling quality and consistency:
- ISO 1302: Specifications for surface texture in technical product documentation, ensuring controlled friction surface quality.
- ISO 2768-1: General tolerances for linear and angular dimensions-applicable to manufacturing toe plates to permissible size deviations.
- ISO 4762: Defines hexagon socket head cap screw specifications used in mounting heel guidings.
- ISO 13715: Guidelines on product documentation focusing on undefined edge forms relevant for precision tooling edges.
- EN 1982: Standards for bronze casting materials for self-lubricating heel guidings.
- EN 10083-2: Requirements for tempered carbon steels used in hardened steel variants of heel guidings.
By adhering to ISO 20929:2018, manufacturers and tool designers benefit from standardized, durable, and effective heel guidings that optimize performance in large-scale metal stamping and forming operations, promoting industry efficiency and safety.

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.
