PRODUCT DESCRIPTION

NSA5454-12ARHX

  • Self‑Locking Insert: Nylon-insert resists loosening under vibration without the need for lockwire.

  • Cadmium Plating: Offers corrosion resistance in salt‑spray, moisture, and hydraulic‑fluid environments.

  • Lightweight Design: Optimised geometry reduces weight while maintaining load capacity.

  • EASA‑Eligible Traceability: Serialised and documented for full compliance with airworthiness records.


  • Secures wing‑to‑fuselage and empennage fittings under dynamic loads.

  • Holds brackets and mounts on turbine and piston engines.

  • Fastens seat tracks, panel mounts, and cabin trim components.

  • Seals and secures manifold housings in fluid control systems.

  • How does the self‑locking feature work?

A nylon insert deforms elastically around the bolt threads, creating friction that prevents back‑off under vibration.

  • Can this nut be reused after removal?

Re‑use is not recommended. Replace after three to five installations to maintain locking performance.

  • How do I inspect the nut before installation?

Check that the nylon insert is free of contaminants, the plating is intact, and threads are undamaged.
