PRODUCT DESCRIPTION

NAS1581F4R5

  • Aerospace-grade material: Heat-treated for strength and fatigue resistance.

  • Precision threads: Manufactured to tight tolerances for smooth engagement and predictable preload.

  • Corrosion-resistant finish: Protective plating or passivation to withstand exposure to fluids and cleaning agents.

  • Standard head form: Fits common wrenches and torque tools for easy installation.


  • Secures bolts on wing and fuselage splice joints during structural assembly and repair.

  • Retains engine-mount and accessory bracket fasteners during ground run-ups and engine checks.

  • Clamps the landing-gear linkage and actuator mounts through repeated extension and retraction cycles.

  • Fastens control-surface hinge and clevis bolts on aileron, elevator and rudder assemblies in flight controls.


  • Can the bolt be reused after removal?

Reuse depends on the condition. Inspect for thread damage, corrosion, or deformation and replace if any defects are found.

  • Is additional locking hardware required?

Follow the applicable maintenance instructions, as some installations require a locknut, prevailing-torque nut, or safety wire as specified.

  • What environments can the bolt handle?

Designed to perform in typical aircraft environments, it can withstand exposure to humidity, fuel, hydraulic fluids, and routine cleaners when used with compatible finishes.
