Description.
The SLEEVE TAPER-HI-LITE™ (STL™) fastener has been developed to provide lightning strike protection to new generation aircraft structure. The STL™ system renders high level mechanical performances allowing for interference fit without causing damage to composite structures.
Features.
- Suitable for very low accessibility areas
- Tightly controlled radial expansion provides lightning strike protection, better electrical conductivity and avoids composite delamination
- Improve fatigue life of metallic structures
- Simple and reliable installation process
- Overlap capability to accommodate thickness variations
Configurator.
