NAS1130-04-10 - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil NAS1130-04-10 by Stanley Engineered Fastening is a high-reliability, military-standard tangless free-running 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 automatically expands elastically outward upon installation to establish a permanent, spring-like retention force without requiring specialized keying or staking. Because it is completely tangless, this insert eliminates the time-consuming process of breaking off, extracting, and counting installation tangs, providing an ideal, debris-free fastening solution that protects critical electronics and aerospace components against foreign object debris (FOD). Yielding a permanently wear-resistant thread, it delivers a conventional internal thread track that lets standard mating bolts turn unhindered while distributing joint stresses evenly to prevent stripping.

Tangless Design Provides robust, permanent internal threading while removing the traditional need for tang break-off and extraction, successfully shielding critical assemblies from foreign object debris (FOD).

Free-Running Profile Delivers a clean, conventional internal thread track that allows standard mating coarse bolts and fasteners to turn completely unhindered without added friction or torque resistance.

High Structural Integrity Compensates for pitch and angle variances within tapped parent metals, dispersing concentrated joint loads evenly to elevate overall assembly fatigue life.

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