Overview
EN 22341:1992 (identical with ISO 2341:1986 and published by CEN) specifies the essential characteristics and metric dimensions for clevis pins with head. The standard covers two product types: type A (without split pin hole) and type B (with split pin hole), for nominal diameters from 3 mm up to and including 100 mm. It aligns product definitions with International Standards and provides examples for correct designation.
This standard is primarily intended to ensure interchangeability, clear designation and consistent application of clevis pins in mechanical assemblies and linking components.
Key Topics
- Scope and types: Defines the two main types of clevis pins with head - type A (no split pin hole) and type B (with split pin hole).
- Metric dimensions: Specifies nominal diameters ranging from 3 mm to 100 mm and corresponding metric sizing conventions.
- Designation guidance: Provides examples for correct product designation to promote clarity in procurement and documentation.
- Reference to international standards: Lists related International Standards and harmonizes terminology and definitions.

Applications
Clevis pins with head standardized by EN 22341:1992 are widely used where reliable detachable pivots or fasteners are required. Typical application areas include:
- Mechanical linkages and joints in agricultural, construction and industrial machinery
- Pivot and hinge connections where accurate pin sizing and head retention are needed
- Repair and maintenance operations where replacement parts must match specified metric dimensions
- Assembly and procurement processes that require unambiguous product designation and compatibility
Using standardized clevis pins improves component interchangeability, reduces specification errors, and supports safer mechanical assemblies by ensuring pin geometry and features meet recognized conventions.
Related Standards
- ISO 2341:1986 - International Standard corresponding to the same subject matter and referenced by EN 22341:1992
- Other CEN or ISO standards for fasteners and pins that define material, strength class or protective treatments may be referenced for complete part specification (consult the EN 22341:1992 bibliographic references for exact cross-references).
For technical procurement, engineering design and maintenance documents, reference EN 22341:1992 to ensure consistent specification of clevis pins with head and to benefit from harmonized designation and metric sizing across suppliers and manufacturers.
