Applications & Benefits
- Load Spreading: Distributes clamping force across fasteners, preventing material deformation
- Corrosion Protection: Resists oxidation in engine bays, fuel tank areas, and environmental control regions
- Low-Profile Design: Perfect for flush installations where aerodynamic drag must be minimized
- Vibration Tolerance: Stainless construction reduces loosening and wear in high-cycle environments
- Aircraft Certification Ready: Meets FAA airworthiness standards for fastener hardware
Maintenance & Installation Advice
- Use per torque specifications outlined in AMM or AC 43.13
- Pair with AN/NAS quality bolts and lock nuts for full hardware system integrity
- Passivated finish must remain intact—avoid scratches or plating damage
- Do not lubricate unless specified; use materials compatible with aircraft operating environment
