Overview
EN 22340:1992 - Clevis Pins Without Head (ISO 2340:1986) is a European standard developed by CEN that specifies the properties and dimensional characteristics of clevis pins without a head. This standard covers products both without split pin holes (Type A) and with split pin holes (Type B) in metric sizes. Applicable nominal diameters range from 3 mm up to and including 100 mm, supporting versatility in various mechanical and engineering applications. EN 22340:1992 references and aligns with International Standard ISO 2340:1986, ensuring international compatibility and uniformity.
Key Topics
-
Product Types: Details two types of clevis pins:
- Type A - Without split pin holes
- Type B - With split pin holes
-
Metric Dimensions: Specifies nominal diameters from 3 mm to 100 mm, facilitating diverse mechanical uses.
-
Standardized Terminology: Provides clear designations and examples for each pin type and size to minimize ambiguity in supply chains.
-
Reference to International Standards: Harmonized with ISO 2340:1986 for global compatibility, supporting cross-border manufacturing and sourcing needs.
Applications
Clevis pins without head, as defined by EN 22340:1992, play a fundamental role across multiple industries due to their simplicity, strength, and standardization. Typical applications include:
- Machinery and Equipment: Used as pivot, hinge, or linkage pins in agricultural, construction, and industrial equipment.
- Automotive Sector: Integral in assembling and linking mechanical components where quick assembly and disassembly are required.
- Aerospace and Rail: Suitable for control systems and mechanical linkages, benefiting from standardized sizing and interchangeable parts.
- General Engineering: Preferred for assembling mechanical joints and temporary structural connections, owing to their reliability and ease of replacement.
The use of clevis pins standardized under EN 22340:1992 ensures high levels of interchangeability, efficient maintenance, and compatibility between manufacturers and suppliers globally.
