Overview

SIST EN 2897:2001 is a European aerospace standard specifying requirements for high-performance screws used in critical aerospace applications. This standard covers pan head screws with an offset cruciform recess, featuring a close tolerance normal shank and short thread, manufactured from alloy steel and cadmium plated for enhanced corrosion resistance. These screws are classified to withstand a tensile strength of 1100 MPa at ambient temperature and maintain performance at elevated temperatures up to 235 °C.

This standard ensures consistent quality and reliability for fastening components in aerospace assemblies where strength, precision, and durability are critical. By adhering to SIST EN 2897:2001, manufacturers and engineers can optimize joint integrity and safety in demanding aerospace environments.

Key Features

  • Screw Type: Pan head design for robust and even load distribution
  • Recess Style: Offset cruciform recess enabling secure torque application and reduced cam-out risk
  • Shank: Close tolerance normal shank ensuring precise fit and minimal play within assemblies
  • Thread Length: Short thread configuration suitable for high-strength applications with limited engagement length
  • Material: Alloy steel for excellent mechanical properties and toughness
  • Coating: Cadmium plating to provide superior corrosion resistance and maintain fastening integrity over time
  • Performance Class: Rated for 1100 MPa tensile strength at ambient temperature and operable at temperatures up to 235 °C

Applications

SIST EN 2897:2001 screws apply primarily in the aerospace industry where secure, high-strength fasteners are essential. Typical use cases include:

  • Aircraft structural assemblies subject to high mechanical stresses
  • Engine components requiring stable fasteners in elevated temperature environments
  • Avionics housing and equipment fastening needing corrosion-resistant hardware
  • Aerospace manufacturing and maintenance processes demanding standardized, close tolerance fastening solutions
  • Critical mechanical joints in commercial and military aircraft construction

Using screws compliant with this standard enhances overall safety, reliability, and performance of aerospace vehicles where fastener failure is not an option.

Related Standards

For aerospace fasteners and hardware, SIST EN 2897:2001 aligns and complements various other international and European standards focusing on fastener performance, testing, and material specifications, such as:

  • EN 1665 - Aerospace series - Fasteners with specified mechanical properties
  • EN 2335 - Aerospace fasteners - Structural bolts and screws in alloy steel
  • ISO 4762 - Hexagon socket head cap screws used widely in aerospace manufacturing
  • MIL-STD-752 and AS9100 - Military and aerospace quality management systems and fastener requirements

Adopting SIST EN 2897:2001 alongside these related standards facilitates compliance with comprehensive aerospace engineering and safety directives.
