NAS1130-08L10DSF - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil NAS1130-08L10DSF by Stanley Engineered Fastening is a high-performance, military-standard tangless screw-locking insert engineered to provide durable, high-strength internal threads in lightweight parent materials. Precision cold-rolled from premium 304 stainless steel wire with a uniform diamond-shaped cross-section, this wire thread insert compensates for pitch and angle variances to optimize joint load distribution. Designed with an advanced screw-locking configuration, it features a series of specialized straight segments or chords on the internal coils that apply a resilient, self-locking torque to the male fastener, preventing it from backing out under extreme vibration or shock. Because it is completely tangless, this insert eliminates the time-consuming process of breaking off and retrieving installation tangs, providing a certified foreign object debris (FOD) free assembly environment. Engineered for high-speed automated production, it features a convenient strip-feed packaging configuration that aligns the inserts on a continuous plastic carrier strip, while a high-grade dry film lubricant coating significantly minimizes friction, galling, and wear during installation and operation.

Tangless Design Provides permanent, high-strength internal threads while completely eliminating the traditional need for tang break-off and extraction, successfully shielding critical assemblies from foreign object debris (FOD).

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.

Strip-Feed Packaging Aligns wire thread inserts on a continuous plastic carrier strip to drastically accelerate assembly throughput when integrated with semi-automated or automated power installation tooling.

Dry Film Lubricant Greatly reduces installation friction and prevents severe thread binding, galling, and material wear under heavy cyclic loads.
