Overview
EN 2649:1995 (adopted as SIST EN 2649:2001) is a CEN aerospace standard that defines the characteristics of pan head, slotted screws threaded to the head, manufactured from alloy steel and cadmium plated. The document classifies these fasteners as 900 MPa (at ambient temperature) / 235 °C, indicating their designated mechanical class and elevated-temperature consideration for aerospace applications.
Key Topics
- Scope and classification
- Covers pan head, slotted screws with threads extending to the head.
- Classification given as 900 MPa (ambient) / 235 °C, used to indicate mechanical performance and temperature applicability.
- Material and surface treatment
- Specifies alloy steel construction and cadmium plating for corrosion protection and surface treatment consistency.
- Form and geometry
- Defines head style (pan head) and drive type (slotted) and that threads are formed or rolled/ cut up to the head.
- Characteristics and conformity
- Specifies the essential characteristics manufacturers and procurers must meet (mechanical class, material, plating and form factors) to assure interchangeability and performance in aerospace contexts.
- Identity and adoption
- Adopted nationally (SIST EN 2649:2001) and published in multiple languages for European aerospace industry use.
Applications
- Aerospace assemblies where compact pan head, slotted fasteners are needed and where parts are exposed to elevated temperatures (up to the classification temperature).
- Aircraft maintenance and repair for replacement parts specified by OEMs or maintenance documents that reference EN 2649.
- Manufacturing and procurement of aerospace components to ensure purchased screws meet the required mechanical class, material and plating.
- Common use-cases include interior fittings, avionics mounting, and other assemblies where specified strength, corrosion protection and head form are required.
Who Uses This Standard
- Aerospace engineers and designers specifying fasteners.
- Fastener manufacturers and heat-treatment/plating suppliers.
- Quality assurance, purchasing and maintenance personnel in aviation organizations.
- Certification and conformity assessment bodies verifying parts meet CEN requirements.
Related Standards
- SIST EN 2649:2001 (national adoption of EN 2649)
- Other CEN/EN and international fastener standards and aerospace fastener specifications (for sizing, testing and performance classes).
