NAS1130-02L15D - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil NAS1130-02L15D by Stanley Engineered Fastening is a high-performance tangless screw-locking insert engineered to establish exceptionally resilient internal threads in lightweight or soft parent materials. Built from precision-formed 304 stainless steel wire with a diamond-shaped cross-section, this military-standard wire insert provides a strong, wear-resistant internal thread that guards assemblies against the damaging effects of vibration, thermal expansion, and contraction. Its advanced screw-locking configuration applies a positive self-locking torque to the male member via specialized chords on the coils, completely securing the joint without sacrificing performance. Because it is completely tangless, this wire insert eliminates the multi-step process of breaking off and retrieving installation tangs, providing an ideal, debris-free fastening solution that protects sensitive aerospace, electronic, and defense assemblies against foreign object debris (FOD).

Tangless Design Provides permanent, wear-resistant threads while completely eliminating the traditional need for tang break-off and retrieval, protecting critical systems from foreign object debris (FOD).

Screw-Locking Mechanism Delivers a resilient internal self-locking torque on the male member through one or more specialized chords on the insert coils to ensure a vibration-proof joint.

High Material Adaptability Seamlessly adjusts to the natural thermal expansion and contraction of the parent material to maintain a permanently anchored fit within the tapped hole.

Premium Wire Construction Features precision-formed, diamond-shaped wire that requires no staking, swaging, keying, locking, or interference fits during installation.
