Overview
EN 22339:1992 - Taper pins, unhardened (ISO 2339:1986) is a CEN standard that specifies the characteristics of unhardened taper pins with metric dimensions. The standard covers nominal diameters from 0.6 mm up to and including 50 mm, aligns with the International Standard ISO 2339:1986, and includes an example of how taper pins should be designated. It is referenced and reproduced by national bodies (for example, the Slovenian adoption SIST EN 22339).
Key Topics
- Product scope: Defines the range of taper pins covered (metric sizes, nominal diameters 0.6–50 mm).
- Characteristics: Specifies essential product characteristics for unhardened taper pins (dimensional and identification requirements are addressed in the standard).
- References to International Standards: Cross-references ISO 2339:1986 and other relevant international standards to ensure harmonized definitions and practices.
- Designation example: Provides an example format for the correct designation of taper pins to aid procurement and documentation.
- Classification: Falls under ICS 21.060.50 (pins, nails), making it part of the fastener and mechanical component standards family.
Applications
EN 22339 is practical for any application requiring unhardened taper pins where accurate metric sizing and consistent designation are important. Typical uses include:
- Locating and securing mating parts in mechanical assemblies
- Dowel and alignment applications in machinery, jigs, and fixtures
- Assembly and repair work in manufacturing, automotive, and machine-tool industries
- Specification for suppliers and procurement of standardized taper pins
Using a standardized reference ensures interchangeability, consistent quality, and clear communication between designers, manufacturers, and suppliers.
Who should use this standard
- Mechanical designers and engineers specifying locating pins in assemblies
- Procurement professionals and fastener suppliers selecting or listing taper pins
- Production and maintenance engineers responsible for assembly or repair
- Quality and inspection personnel verifying conformity to standard dimensions and designations
- Standards bodies and technical libraries referencing harmonized European/ISO documents
