Overview

SIST EN 4133:2009 is a European Standard developed by CEN (European Committee for Standardization) for the aerospace industry. It specifies the characteristics of normal hexagonal head bolts with a coarse tolerance normal shank and a long thread, manufactured from titanium alloy and coated with aluminium using the IVD (Ion Vapor Deposition) process. The bolts are classified for use at a minimum tensile strength of 1,100 MPa at ambient temperature, and up to operating temperatures of 425°C.

This standard ensures product performance and interoperability for aerospace fasteners, helping aerospace manufacturers, suppliers, and maintenance providers meet industry expectations for quality and safety when working with titanium alloy bolts.

Key Topics

  • Bolt Description and Classification

    • Normal hexagonal head, coarse tolerance normal shank, long thread
    • Titanium alloy construction for high strength-to-weight ratio
    • Aluminium IVD coating for enhanced corrosion resistance and high-temperature protection
    • Classification: 1,100 MPa minimum tensile strength at ambient temperature, up to 425°C elevated service temperature

  • Material and Surface Treatment

    • Titanium alloy in compliance with industry procurement specifications
    • Surface treatment based on MIL-DTL-83488D, providing a durable aluminium IVD coating
    • Optional post-treatment lubrication for ease of installation and added protection

  • Dimensions and Tolerances

    • Defined in millimetres, including diameter, length, and thread forms
    • Dimensional tolerances specified for reliable fit and interchangeability

  • Designation and Marking

    • Systematic part numbering for bolted products
    • Marking requirements in accordance with EN 2424 for traceability

  • Technical and Quality Requirements

    • References to related quality management standards, including EN 9100 and EN 9133
    • Compliance with ISO specifications for threads and tolerances
    • Specifies procedures for qualification, marking, and approval of aerospace bolts

Applications

SIST EN 4133:2009 bolts are critical components in aerospace engineering, specifically designed to withstand demanding operational conditions. Typical applications include:

  • Aircraft Structures: Used in primary and secondary structural joints where high strength, reliability, and temperature resistance are needed.
  • Engine Assemblies: Suitable for fastening engine components exposed to high temperature and vibration.
  • Spacecraft and Defense Systems: Employed in environments where lightweight, high-performance materials with excellent corrosion resistance are vital.
  • Aerospace Maintenance and Repairs: Used as replacement fasteners during overhaul or maintenance activities to ensure continued safety and airworthiness.
  • Other High-Performance Sectors: Where similar engineering requirements exist, such as high-speed rail and advanced automotive sectors.

The use of titanium alloy and aluminium IVD coating provides enhanced protection against corrosion, extends bolt life, and ensures performance consistency under extreme conditions.

Related Standards

SIST EN 4133:2009 makes reference to several related industry and international standards for aerospace fasteners and quality management:

  • EN 2424: Marking requirements for aerospace products
  • EN 9100: Requirements for quality management systems in the aerospace sector
  • EN 9133: Qualification procedures for aerospace standard parts
  • ISO 3353-1: Specifications for external thread lead and runout
  • ISO 5855-2: Limit dimensions for bolts and nuts with MJ threads
  • ISO 7913: Tolerances of form and position for metric bolts and screws
  • ISO 9152: Procurement specification for titanium alloy bolts, strength class 1,100 MPa
  • MIL-DTL-83488D: Specification for high purity aluminium coatings

Conformance to these standards ensures compatibility, safety, and quality across aerospace assemblies and optimizes the supply chain for fastener procurement and use.
