Overview

SIST EN 2889:2009 is a European standard published by the Slovenski inštitut za standardizacijo (SIST) that specifies the requirements for aerospace metric bolts with normal hexagon heads, coarse tolerance shanks, and short threads, manufactured from alloy steel and finished with cadmium plating. These bolts are classified for a minimum tensile strength of 900 MPa at ambient temperature and are designed to withstand operation at temperatures up to 235 °C. The standard focuses on defining dimensional characteristics, material properties, surface treatment, and marking for aerospace industry compliance.

Key Topics

• Product Scope: Metric bolts with normal hexagonal heads, coarse tolerance, normal shank, and short thread.
• Material: Alloy steel with a minimum tensile strength of 900 MPa at ambient temperature.
• Surface Finish: Cadmium plating applied per EN 2133, designed for corrosion resistance and temperature stability up to 235 °C.
• Configuration: Multiple diameter and length codes, with optional features for lockwire or split pin holes.
• Marking: Detailed requirements for bolt identification and traceability in compliance with EN 2424.
• Dimensional Compliance: Dimensions and tolerances follow ISO 3193 and ISO 5855-2, ensuring interchangeability and reliability.
• Performance Classification: Designed for high mechanical strength and durability in demanding aerospace environments.
• Quality Assurance: Manufacturing processes and supplier qualifications must align with EN 9100 standards.

Applications

The SIST EN 2889:2009 standard finds practical value in the following areas:

• Aerospace Structures: Used in aircraft frames, engine assemblies, landing gear, and critical systems requiring reliable high-strength fasteners.
• Maintenance and Repair: Essential for MRO (Maintenance, Repair, and Overhaul) teams ensuring replacement parts meet industry benchmarks for quality and safety.
• New Aircraft Manufacturing: Adoption of these standardized bolts enables manufacturers to streamline procurement, facilitate international collaboration, and support regulatory compliance.
• Defense and Space Industries: Beyond civil aviation, these cadmium-plated alloy steel bolts are suitable for defense technology and satellite structures where environmental resistance and high mechanical performance are mandatory.
