Overview
EN 2911:1995 (adopted as SIST EN 2911:2001) is a CEN aerospace standard that specifies the characteristics of self-locking shank nuts manufactured from heat-resisting steel FE-PA92HT (A286) with silver plating. The standard defines a mechanical classification of 1 100 MPa (at ambient temperature) and resistance up to 650 °C, targeting high-temperature aerospace applications where reliable fastening and elevated temperature performance are required.
This standard is indexed under ICS 49.030.30 (Nuts) and is used to ensure component interchangeability, material traceability and consistent performance across aerospace assemblies.
Key Topics
- Material specification: Use of heat-resisting steel FE-PA92HT (A286) suitable for elevated temperatures and demanding service conditions.
- Locking function: Self-locking shank nut design to maintain clamping force and resist loosening under vibration and thermal cycling.
- Surface treatment: Silver plating for corrosion protection and contact performance in aerospace environments.
- Performance classification: Designation of mechanical capability as 1 100 MPa at ambient temperature and rated for 650 °C service.
- Scope and conformity: Standard applies to aerospace series shank nuts and supports consistent procurement and quality control practices.
Applications
EN 2911:1995 is intended for aerospace engineering and manufacturing contexts where fasteners must perform reliably under high temperature and mechanically demanding conditions. Typical applications include:
- High-temperature engine components and assemblies
- Airframe areas exposed to thermal gradients and vibration
- Critical fastening points requiring predictable locking performance
Benefits of specifying nuts to EN 2911 include:
- Traceable material and process requirements that help manufacturers and procurement teams verify compliance
- Improved reliability of assemblies operating at elevated temperatures
- Compatibility across suppliers through a common classification and material designation
Related Standards
- CEN EN standards for aerospace fasteners and material testing (consult for complementary test methods and dimensional standards)
- National adoptions such as SIST EN 2911:2001 (Slovenian adoption of EN 2911:1995)
For engineers and procurement specialists, EN 2911:1995 provides a focused specification for self-locking shank nuts in FE-PA92HT (A286), silver-plated, enabling consistent selection of high-temperature, high-strength locking fasteners in aerospace assemblies.
