Product Description
The Heli-Coil NAS1130-04L10D by Stanley Engineered Fastening is a military-grade tangless screw-locking insert meticulously designed to establish heavy-duty, resilient internal threads in low-strength parent materials. Cold-rolled from precision-formed 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. Engineered with an advanced screw-locking configuration, it features one or more straight segments or chords on the coils that apply a resilient self-locking torque to the male bolt, ensuring a vibration-resistant joint. Because it is completely tangless, this wire insert eliminates the time-consuming process of breaking off and retrieving installation tangs, providing a flawless, debris-free fastening solution that protects critical electronics and aerospace components against foreign object debris (FOD) while delivering a permanent, wear-resistant thread.
Tangless Design Provides permanent, high-strength internal threads while completely eliminating the traditional need for tang break-off and extraction, shielding sensitive electronics from foreign object debris (FOD).
Screw-Locking Mechanism Grips the male bolt or screw with a resilient internal locking thread, ensuring a secure, vibration-proof joint without the need for lock-washers or auxiliary locking devices.
High Material Adaptability Automatically expands outward upon installation to anchor itself permanently, providing wear-resistant threads that dynamically adapt to material expansion and contraction.
Resilient Wire Construction Utilizes a continuous helically wound diamond profile that distributes stresses evenly across the tapped parent material to shield assemblies from thread stripping and wear.
