NAS1130-3L10DSF by HELI-COIL

The Heli-Coil NAS1130-3L10DSF by Stanley Engineered Fastening is a high-reliability, military-standard tangless screw-locking insert meticulously designed to establish permanent, high-strength internal threads in low-density parent metals. Cold-rolled from premium 304 stainless steel wire with a precise diamond-shaped cross-section, this wire thread insert compensates for pitch and angle variances to optimize joint load distribution. Engineered with an advanced screw-locking configuration, it features a series of specialized straight segments or chords on the internal coils that exert a resilient, self-locking torque to the male fastener, preventing it from backing out or loosening under intense vibration, shock, or thermal cycling. Because it is completely tangless, this wire insert eliminates the time-consuming process of breaking off and retrieving installation tangs, providing an ideal, debris-free fastening solution that protects critical electronic and aerospace components against foreign object debris (FOD). Additionally, its convenient strip-feed packaging configuration aligns the inserts on a continuous plastic carrier strip for high-speed integration with automated or semi-automated power installation tools, while a high-grade dry film lubricant coating significantly minimizes friction, galling, and wear.

Tangless Design Provides permanent, high-strength internal threads while completely eliminating the traditional need for tang break-off and extraction, shielding sensitive equipment 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 power installation tooling.

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