NAS1130-04-15 - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil NAS1130-04-15 by Stanley Engineered Fastening is a high-performance, military-standard tangless free-running insert engineered to establish reliable, heavy-duty internal threads in lightweight or soft parent materials. Cold-rolled from premium 304 stainless steel wire with a precision diamond-shaped cross-section, this wire thread insert compensates for pitch and angle variances to optimize joint load distribution. 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 sensitive aerospace, electronic, and defense assemblies against foreign object debris (FOD). It automatically expands outward upon installation to establish a permanent, wear-resistant thread that defends critical, fine-thread connections against stripping and structural erosion.

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).

Free-Running Profile Delivers a clean, conventional internal thread that allows standard bolts and fasteners to turn freely through the precision-formed profile.

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.v
