SIST EN 2650:2001 - Aerospace series - Screws, pan head, slotted, threaded to head, in corrosion resisting steel, passivated - Classification: 600 MPa (at ambient temperature)/425 °C

Overview

EN 2650:1996 is a CEN aerospace standard that specifies the characteristics of pan head, slotted screws threaded to the head, made from corrosion resisting steel and passivated. The standard is part of the aerospace series of fastener specifications and carries a classification shown as 600 MPa (at ambient temperature) / 425 °C. EN 2650 covers dimensional and material characteristics appropriate for high-reliability applications where corrosion resistance and defined mechanical performance are required.

Key Topics

  • Fastener type: Pan head, slotted screw with threads extending close to the head (often described as “threaded to head”).
  • Material: Corrosion resisting steel (stainless or similar alloys) subjected to passivation to improve corrosion performance.
  • Classification: Marked 600 MPa / 425 °C, indicating its design/intended mechanical classification at ambient conditions and an associated temperature reference noted in the title.
  • Surface treatment: Requirements for passivation to reduce corrosion and improve long-term durability in service environments.
  • Dimensional and acceptance criteria: The standard defines the essential physical characteristics and acceptance-class intent for aerospace use (e.g., head form, slot geometry, and thread extent), ensuring interchangeability and compatibility with mating parts. Note: EN 2650 provides classification and characteristic requirements; consult the full standard text for precise dimensional tables, tolerances and inspection details.

Applications

EN 2650 is intended for aerospace and other high-reliability industries where:

  • Corrosion resistance and consistent mechanical performance are critical (airframes, avionics enclosures, interior and exterior assemblies).
  • Fasteners must be interchangeable and traceable to a recognized standard for procurement, quality control and maintenance.
  • Designers, purchasing departments, maintenance/repair organizations, and fastener manufacturers require a defined specification for pan head slotted screws in corrosion resisting steel.

Typical users:

  • Aerospace design and structural engineers
  • Fastener manufacturers and suppliers
  • Quality assurance and inspection teams
  • Maintenance, repair and overhaul (MRO) organizations

Related Standards

  • Other aerospace fastener standards covering different head types, materials and strength classes.
  • Material and surface treatment standards for stainless steels and passivation processes.
  • Procurement and quality standards used by aerospace OEMs and MROs.
