NAS1130-02L10 - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil NAS1130-02L10 by Stanley Engineered Fastening is a military-standard tangless screw-locking insert engineered to establish high-integrity, wear-resistant internal threads in soft parent metals like aluminum and magnesium. Precision cold-rolled from high-grade 304 stainless steel wire with a uniform diamond cross-section, this insert features a tangless bi-directional design that completely eliminates the need for tang break-off or retrieval, eradicating foreign object debris (FOD) risks in critical aerospace and electronics assemblies. Its advanced screw-locking configuration incorporates a series of straight chord segments on the internal coils that exert a resilient, self-locking torque on the male fastener, preventing rotational loosening under severe shock and vibration without requiring lock-washers or auxiliary locking devices.

Tangless Bi-Directional Design Eliminates installation tangs to prevent foreign object debris (FOD) issues, allowing quick, non-destructive installation and easy adjustment from either end.

Screw-Locking Mechanism Grips the male bolt or screw with a series of specialized straight segments on the internal coils, ensuring a secure, vibration-proof joint without requiring lock-washers or auxiliary locking devices.

Military Specification Certified Manufactured to strict NAS1130 standards, guaranteeing consistent performance and dimensional accuracy in mission-critical hardware assemblies.

Resilient Wire Construction Utilizes a continuous helically wound diamond profile that handles thermal expansion and contraction elastically while safeguarding against thread stripping and wear.
