NAS1130-02-10 - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil® Tangless® Free-Running Insert (Part Number: NAS1130-02-10) provides high-strength, permanent internal threads while entirely eliminating the risk of foreign object debris (FOD) in flight-critical and high-vibration systems. Cold-drawn from ultra-smooth 304 stainless steel wire, this precision-formed component eliminates the conventional drive tang, bypassing the steps of tang break-off, retrieval, and accountability. It features an bidirectional design with notch-driven installation, distributing load forces uniformly across the tapped host material to prevent thread stripping and maximize performance in modern engineering configurations.

Tangless Infrastructure Removes the requirement for a physical installation tang, saving significant production time by entirely skipping the break-off and component extraction process.

Zero FOD Risk Guarantees an absolute lack of residual debris left within closed assemblies, meeting strict aerospace compliance protocols.

Wear-Resistant Construction Utilizing a diamond-shaped profile work-hardened to a tensile strength over 200,000 PSI, protecting threads from premature erosion and stripping.

Bi-Directional Alignment Built with driving notches on both ends of the wire profile to streamline bulk automatic feeding without orientation errors.
