Technical description and scope of the EN 2931 standard
The EN 2931 standard regulates the design parameters and technical requirements for high-strength T-head bolts. These fasteners are characterized by a lightweight shank design and an increased thread length. The material used is heat-resistant FE-PA92HT steel (internationally known as A286), which allows these components to be used in critical aerospace engineering assemblies.
Key performance characteristics according to the standard classification:
- Tensile strength: 900 MPa (under normal conditions).
- Operating temperature range: up to +650 °C.
- Specialization: critical joints in aircraft construction.
The engineering department of EV Group China provides fasteners that meet the requirements of EN 2931, ensuring precision compliance with the geometry and properties of the A286 heat-resistant alloy for operation in extreme thermal conditions.
