NAS1130-02L10D - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil Stanley Engineered Fastening NAS1130-02L10D is a military-standard tangless screw-locking insert designed to establish exceptionally resilient, internal-locking threads in high-performance aerospace and defense assemblies. Manufactured from cold-rolled 304 stainless steel, this insert utilizes a series of straight segments or "chords" on its interior coils to exert a positive self-locking torque directly onto the male fastener. Because it features a completely tangless design, it eliminates the risk of foreign object debris (FOD) by entirely removing the need for tang break-off or retrieval procedures, creating an incredibly clean installation that permanently secures components against severe vibration and shock loosening.

Tangless Design completely eliminates the need for manual tang break-off and post-installation retrieval, entirely mitigating the risk of foreign object debris (FOD) in critical enclosures.

Screw-Locking Mechanism uses internal chorded coils to deliver robust self-locking torque directly onto the male bolt, providing elite joint protection without separate locking hardware.

304 Stainless Steel Construction provides an extremely high work-hardened tensile strength and durable surface finish to guard parent materials against wear and thread striping.

Dry Film Lubricant Coating minimizes installation friction and optimizes torque-tension relationships, ensuring smooth assembly and preventing high-velocity thread binding.
